Number of configured ADC channels is currently only defined in board
level section, typically in xxx_adc.c file. This commit introduces
ioctl command ANIOC_GET_NCHANNELS that returns the number of configured
channels which is determined by the driver code. The change can allow the
applications to be more flexible when it comes to multiple ADC devices
with different number of configured channels.

PWM drivers currently use channel number 0 for the channels that are not
used by the application. This commit adds number -1 which indicates that
all following channels are not configured and that the loop can be broken.

Cleaning during `clean_context` had the issue of remaking everything
when `menuconfig` was issued. That's because `menuconfig` has a

Summary:
- This commit changes spinlock APIs (spin_lock_irqsave/spin_unlock_irqrestore)
- In the previous implementation, the global spinlock (i.e. g_irq_spin) was used.
- This commit allows to use caller specific spinlock but also supports to use
g_irq_spin for backword compatibility (In this case, NULL must be specified)
Impact:
- None
Testing:
- Tested with the following configurations
- spresnse:wifi, spresense:wifi_smp
- esp32-devkitc:smp (QEMU), sabre6-quad:smp (QEMU)
- maxi-bit:smp (QEMU), sim:smp
- stm32f4discovery:wifi

The calls via RTC API weren't fast enough for the edge case
of minimum counter value, resulting in the timer never
expiring as the counter had already passed the compare value.
This now uses direct register access functions and also
gets the latest counter value in edge case.
This bug made certain values of DRIVE setting
to be wrongly applied (which can be dangerous
under certain situations since for example H0D1
was mapped to H0H1).
This change improves upon current support for pin interrupts. Before,
a pin interrupt was handled (with nrf52_gpiote_setevent) using one
of the eight available GPIOTE channels. Moreover, it didn't event let
the user specify which channel to use (simply tried to get a free one).
Also, it was buggy since it did not consider unsetting the callback.
Besides GPIOTE channels, there is another way to deal with pin interrupts.
The GPIO peripheral is capable of generating a PORT event
(for the whole GPIO port) depending on the pin SENSE configuration
(HIGH or LOW, or NONE) and GPIO DETECTMODE register
(latching or non-latching).
This change then renames nrf52_gpiote_setevent into nrf52_gpiote_set_ch_event,
maintaining functionality of original function, but now allows specifying
channel (and correctly handles unsetting the callback). Then, a
new nrf52_gpiote_set_pin_event is added, which allows to set a callback
for a given pin. During initialization, interrupt for the PORT event is
enabled and handled in such way that for each pin whose corresponding
bit in LATCH register (indicates the result of pin SENSEing) the
callback for this pin will be invoked. This mechanism means that
every pin can get an ISR. It also avoids using GPIOTE channels for this
purpose which carry higher current consumption.
This new per-pin callback mechanism has some added memory requirement
so it can be disabled and its default is dependant on DEFAULT_SMALL.
When disabled, a callback for the PORT event can be set directly
with nrf52_gpiote_set_port_event
There was only one use of nrf52_gpio_setevent() which was migrated
into nrf52_gpio_set_ch_event() passing channel zero.
This separation allows to interact with the watchdog from OS code,
for example initiating the watchdog very early on boot. Moreover,
these changes make the lower-half driver support an already running
watchdog, which may happen if there's a bootloader which already
started it.
cfsetispeed() now stores baud rate to c_cflag member of
struct termios, so it must not be overridden later on.

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.
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.

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).
