Summary:
- Modify arm_intstack_base() to return "top" of the IRQ stack for the current CPU
- This change fixes IRQ stack dump information for ARM SMP
- Add arm_intstack_alloc() to return "bottom" of the IRQ stack for the current CPU
- Also, these functions are now implemented in xxx_irq.c (imx/cxd56/lc823450)
- up_color_intstack() and up_check_intstack() now call arm_intstack_alloc()
- These semantics are now consistent with non-SMP case
- up_color_intstack() now initializes whole IRQ stack region for SMP
- Adjust IRQ stack top address for each CPU (e.g. -8)
- Fix setintstack to handle in case of NCPUS=1 (cxd56, lc823450)
- Adjust INTSTACK_SIZE to 8 bytes alignment (cxd56, lc823450)
- Refactor setintstack for lc823450
- Remove old IRQ stack coloring code from up_irqinitialize() (lc823450)
- Introduce g_cpu_intstack_top for lc823450
- Refactor header files
Impact:
- Affects imx6/cxd56xx/lc823450 SMP with interrupt stack enabled
Testing:
- Tested with sabre-6quad:smp (with QEMU, NCPUS=1 and 4)
- Tested with spresense:wifi_smp (NCPUS=1 and 2)
- Tested with lc823450-xgevk:rndis (NCPUS=1 and 2)

cfsetispeed() now stores baud rate to c_cflag member of
struct termios, so it must not be overridden later on.

* Fix nxstyle errors; nxstyle was complaining about lack of a
space after comma because of the presence of line
continuation backslashes immediately after the comma.
Removed these backslashes as they are not necessary: these
lines are typedefs, not preprocessor defines.
arch/arm/src/tiva/cc13xx/cc13x2_v2_trim.c:
* Fix nxstyle errors.
* No functional changes; however modified one function,
trim_wakeup_fromshutdown(), to avoid blocks that existed
only to declare variables mid-function; nxstyle was
complaining about the positions of the opening and
closing braces of those blocks.

Summary:
- The handle_irqreq() is used for remote IRQ control.
- The logic is called via IPI (Inter-Processor Interrupt)
- And the handler should handle only one request
- However, I noticed that the handler handles up to two requests
- This commit fixes this issue
Impact:
- Affects SMP cases only
Testing:
- Tested with spresense:wifi_smp

Not all boards have an interrupt line from the phy to
the Soc. This commit allows the phy to be polled for
link status.
This may not work on all MAC/PHY combination that
have mutually exclusive link management and operating
modes. The STM32F7 and LAN8742AI do not have such a
limitation.
Summary:
- I found an issue with up_interrupt_context() when testing.
- And finally found that up_interrupt_context() is not atomic.
- This commit fixes the issue
Impact:
- Affects SMP only
Testing:
- Tested with spresense:wifi_smp and sabre-6quad:smp (qemu)

There was no error handling before and it would block on common
cases like NACK which meant that you could not use the i2ctool
to perform a scan of the bus.
This does not handle the interrupt flow which also has incomplete
error handling.
When the Head to Tail relationship was H < T, then
only the tail to end of buffer was sent.
The fix is: In the txdma completion to do a second
the DMA operation using nbuffer if the nlength is
non zero.
stm32f7:serial UART5 use actual size
UART5 was using the CONFIG_UART5_TXBUFSIZE
not the UART5_TXBUFSIZE_ADJUSTED.
Since the buffer size was adjusted up, this
has no dcache implications.
If the UART5_TXBUFSIZE_ADJUSTED is larger
then CONFIG_UART5_TXBUFSIZE it will present
a larger usable buffer to the system's
serial driver.
This implements the missing callback hooks nrf52_spi0/1/2/3register
that are usually used with mmcsd for card detection.
This also stubs out the missing spi trigger function which is not
used on this platform.
The card detect was tested with the nRF52-feather board and a
modified KeyBoard FeatherWing.

The current EasyDMA implementation will fail if a transfer of over
255 bytes is requested with no warning.
Also we do not set the RX and TX transfer lengths to 0 if the
buffer is NULL which can cause data to be written to the old
address as well as cause unexpected transaction lenghts.
Example:
transfer 1:
rx_len = 10
rx_buff != NULL
tx_len = 10
tx_buff != NULL
transfer 2:
rx_len = 2
rx_buff != NULL
tx_buff == NULL
Total transaction length for the second would be 10 because it
would still be using the old rx length of 10 and would
corrupt data in the old rx buffer.

EXTRAFLAGS is already applied to *FLAGS in board's Make.defs (and
it applies to whole build, not just arch-code). EXTRAFLAGS is passed
around each make call to the complete build.
KDEFINE is already added to EXTRAFLAGS in main Makefile so no need
to add it again in arch-level Makefile

This commit exends systimer options for nRF52 arch. It is possible
to use ARM SysTick either for tickless or non-tickless mode. Also,
it is possible to use the RTC peripheral for tickless mode. This
also re-enables support for WFI/WFE sleep if RTC is used, since
this counter continues to run in this mode (in contrast to SysTick).
