This commit adds support for dead time delay to SAMv7 PWM driver. The
dead time can be used to delay an active PWM output at the begining
of the period. This can be used for H bridge control for example.
The values are to be set from the application level. It is required
to allow config option PWM_DEADTIME in order to support dead time delay.

Hardware flow control for serial requires the usage of DMAC channels
which is not yet supported for SAMv7 MCU. However the same config option
CONFIG_SERIAL_IFLOWCONTROL is also used for USB CDC/ACM flow control which
works well. Therefore the warning message should be raised only if
flow control is configured for USART driver and not for USB CDC/ACM.

A list of breaking changes:
- SoftDevice libraries was renamed and libaries are now cmpatible with all platfroms with a given faimily.
- The random number generator was decoupled from the controller and must now be provided by the user.
We use arc4random_buf NuttX API for this.
- sdc_support_ API must be called before sdc_cfg_set()
- update public API terms to Bluetooth Core Specification v5.3 (mainly change slave/master to central/peripheral)
NuttX NRF52 configuration options properly updated.
- BLE features are supported only if the proper BLE role is selected
- sdc_hci_evt_get() and sdc_hci_data_get() have been replaced by sdc_hci_get()
This commit adds configurable fault protection to SAMv7 PWM driver.
The fault input can be used from peripherals as ADC or GPIO inputs.
Inputs from GPIO have configurable polarity (high or low). The PWM output
is automatically set to zero if fault input is active and restored
if fault input is not actived.

- Add retry timeout to prevent inifinite loop
- Change the register operation of power control
- Add exclusive control by semaphore into some functions
- Add short delay until power control is reflected
This commit enhances ADC and PWM drivers with option to trigger ADC
conversion with events generated by PWM comparison units.
The generation of PWM events is handled by comparison units set up from
Kconfig option SAMV7_PWMx_TRIGn. ADC triggering from PWM can be selected
by AFECn_PWMTRIG option.

SAMv7 PWM driver supports complementary PWM output if both pins (H and L)
are defined and configured. This commit adds a configuration option to
configure the complementary L pin.
The pin definition has to be provided by board level support.

Summary:
- I noticed that there are two kinds of descriptors for imxrt_enet.c
- The first one is the legacy descriptor and its size is 8bytes.
- The second one is the enhanced descriptor and its size is 32bytes.
- In both cases, we can not use a descriptor chain like stm32.
- Considering cache line alignment, the second one is perfect because
one descriptor fits the Cortex-M7 cache line which would fix networking
stability issues in d-cache write-back mode.
Impact:
- imxrt ethernet in d-cache write-back mode
Testing:
- Tested with ixmrt1060-evk:netnsh_dcache_wb (will be added later)

This reverts commit 62c15c03d3.
Fix warning: the choice symbol STM32_FLASH_CONFIG_G (defined at arch/arm/src/stm32/Kconfig:1275) is selected by the following symbols, but select/imply has no effect on choice symbols
- ARCH_CHIP_STM32F412ZG (defined at arch/arm/src/stm32/Kconfig:1014)
Generic drivers shoud not use architecture related config options like
CONFIG_SAMV7_PWM. This commit adds PWM pin overwrite under generic
configuration option CONFIG_PWM_OVERWRITE.
Now the overwrite can be used on other architectures as well or can be
completely disabled for SAMv7.

When I checked how this register was set I discovered that 128 was not
accepted by the H7 but 64 was ok. Looking at the STM32Cube's HAL it
seems to be only 64 words long, however, the reference manual claims
otherwise.
I have opened a discussion on the ST community forum
https://community.st.com/s/question/0D73W000001nzqFSAQ
but unfortunately not received an answer yet.
In the meantime, I think, we should update this to what I found to be
working though.

Current implementation supports the trigger generation only from timer
capture on period value. This is sufficient for PWM synchronization but
may not be enough for other purposes as ADC triggering for example.
This change adds an option to generate the trigger based on a duty
cycle value.

The function call dac_txdone(&g_dac1dev) was not contained in ifdef
section. This was cousing compilation error if only DAC1 was configured
as the structure g_dac1dev is defined only if DAC0 is used.
This commit fixes the error and ensures the function is called only if
corresponding DAC is configured.

In the lower half UART driver for Tiva architecture (TM4C12x), adding
the TIOCxBRK ioctl calls, which allow an application to transmit a BSD
compatible line BREAK. TIOCSBRK starts the BREAK and TIOCCBRK ends it.
This architecture supports BSD-style BREAK in hardware. We write to
the BRK bit (bit 0) of the UART Line Control register (UARTLCRH) to
start the BREAK, which begins after the UART finishes shifting out the
current character in progress, if any, including its stop bit(s), and
continues indefinitely until we write to the BRK bit again to stop the
BREAK.
* arch/arm/src/tiva/Kconfig
(config TIVA_UART_BREAKS): New. Appears as CONFIG_TIVA_UART_BREAKS
in code.
* arch/arm/src/tiva/common/tiva_serial.c
(struct up_dev_s): Add new field 'brk' to indicate line break in
progress when built with CONFIG_TIVA_UART_BREAKS.
(up_ioctl): Add cases for TIOCSBRK to turn BSD-compatible break on
unconditionally and TIOCCBRK to turn break off unconditionally.
(up_txint): Block enabling TX interrupt if line break in progress.
This is similar to the STM32F7 implementation.
* arch/arm/src/tiva/common/tiva_serial.c:
(up_ioctl): PR #8406 (commit 1edec0aaa1) added support for
configuring the serial port's CTS/RTS flow control at runtime using
termios when built with CONFIG_SERIAL_TERMIOS and either or both of
CONFIG_SERIAL_OFLOWCONTROL and CONFIG_SERIAL_IFLOWCONTROL. However,
a runtime sanity check left over from before prevented this from
working: When processing ioctl TCSETS, we would return -EINVAL if
one or both of CCTS_OFLOW and CRTS_IFLOW were requested, which was
not deserved if the requested features were in fact supported.
Fixing the sanity check so it depends on features actually
configured.
The function is not relevant any longer, remove it. Also remove
save_addrenv_t, the parameter taken by up_addrenv_restore.
Implement addrenv_select() / addrenv_restore() to handle the temporary
instantiation of address environments, e.g. when a process is being
created.
Detach the address environment handling from the group structure to the
tcb. This is preparation to fix rare cases where the system (MMU) is left
without a valid page directory, e.g. when a process exits.

This is a follow-up to PR #6548, which added UART CTS/RTS support for
Tiva (TI TM4C12x) microcontrollers. This follow-up makes it possible,
when termios support is enabled with CONFIG_SERIAL_TERMIOS and CTS/RTS
support is enabled with CONFIG_SERIAL_OFLOWCONTROL and/or
CONFIG_SERIAL_IFLOWCONTROL, to query whether CTS/RTS are on/off at
runtime by utilizing ioctl TCGETS and to turn CTS/RTS on/off at runtime
by utilizing ioctl TCSETS.
* arch/arm/src/tiva/common/tiva_serial.c
(up_set_format): Because this function is called from ioctl TCSETS to
modify UART settings, and that IOCTL now respects CCTS_OFLOW and
CRTS_IFLOW, move setting/clearing of Tiva UART's CTL register's RTSEN
and CTSEN bits here...
(up_setup): ...from here.
(up_ioctl): For TCGETS, populate CCTS_OFLOW and CRTS_IFLOW bits as
appropriate. For TCSETS, populate priv's oflow and iflow from
supplied CCTS_OFLOW and CRTS_IFLOW bits.
Thanks to Petro Karashchenko for review and suggested fixes.

The lower-half serial driver for Tiva (TI TM4C12x) microcontrollers supports
termios, but Kconfig never enabled this support because we were missing the
ARCH_HAVE_SERIAL_TERMIOS configs. This is now enabled, allowing termios support
to be enabled with CONFIG_SERIAL_TERMIOS.
* arch/arm/src/tiva/Kconfig
(config TIVA_UART0 thru TIVA_UART7): Select ARCH_HAVE_SERIAL_TERMIOS.
