Config option IMXRT_ADCx_ETC can now be used to select an external HW
trigger to be used instead of continous trigger. Continous trigger is
used if IMXRT_ADCx_ETC = -1 (default option). Otherwise the source signal
is routed through XBAR and used as a trigger.
Hardware triggering is currently limited to maximum of 8 channels.
HW trigger is automatically disabled if there are more than 8 channels.
The external triggering was tested with PWM signal as a source.

This commit allows the PWM modules to be synchronized by an external
signal (other PWM module for example). The sync source can be selected
from configuration.
PWM module can also now generate a trigger when its timer reaches the duty
cycle. This trigger is used for the synchronization of other modules. It
can also be used for triggering ADC for example in the future.
Thanks to Rastislav Pavlanin and Jan Spurek from NXP support for
suggestion which helped to solve the inter-module PWM synchronization
task.

This patch adds corrected implementation of FLASH memory to be used
with progmem driver for use with mtd filesystems like nxffs or smartfs.

This patch adds to the nucleo-wl55jc previously implemented EXTI support.
Button support with nuttx's button driver is added.
I've written small example to show how to use GPIO EXTI. B3 button can be
used (selectable via Kconfig) to toggle Red LED.
I've added new defconfig for demo purposes. I've included there config
and enabled example programs that are meant to demonstrate functions of
the board and does not really have a place in real world project. Like
Red LED can be toggled with B3 button, or LED example that flashes LEDS,
or button example to show which button has been pressed.

v1 -> v2:
Suggested by: Petro Karashchenko
- change (1 << n) to (1 << (n)) in macro definition
- change 1 << X to (1 << X) in code
- fix alignment
v2 -> v3:
Suggested by: Petro Karashchenko
- I was supposed to change (1 << pin) to 1 << pin, not the other way around:)
This patch adds documentation for both stm32wl5 chip family and
nucleo-wl55jc board. I've kept the same directory structure for
arm/stm32 as in arch/ and boards/ directories.

Multiple files were badly formatted, which resulted in many
warnings. This made it harder to check for errors in newly
written documentation.
What's worse, badly formatted text resulted in butchered
output in generated html.
This patch fixes most of the errors, but alas, not all of
the errors can be fixed. Anyway, this should be way easier
to spot errors in newly written docs now.
