The nucleo evaluation boards can be enhanced with shields for additional
functionality. Flat device tree overlays can be used to configure and
support these shields. Regrettably leds can not be simply added due to
a missing label. Tag leds with a label.

Add gpio-keys codes for all boards. These are mostly INPUT_KEY_0 and so
on but I've used some more specific ones where it was obvious that
there's something else on the boards.

Prescaler was misplaced in pwm binding, instead of timers binding.
For example, TIM6/TIM7 doesn't have PWM capability,
but have a prescaler.
This change also prepares the introduction of timer based counter
(which requires prescaler at timer level)

Move SPI pin configuration to device tree for all STM32 based
boards.
This should not bring any change in pin configuration.
Though, some adjuments have been made on following boards for
coherency:
* b_l4s5i_iot01a1: Removed "very-high-speed" on SPI3 MOSI pin.
Tested with no impact.
* black_f407zg_pro: SPI1 pins configured but not SPI1 node.
Removed pin config as not documented neither.
* sensortile_box: SPI2 pins configured but not SPI2 node.
Removed pin config as not documented neither.
* nucleo_g431rb/nucleo_g474re/nucleo_l476rg/nucleo_l4r5zi:
SPI2 and SPI3 pins were configured but missing.
Added since they were documented.

Following other drivers, Kconfig based instances are now entirely
removed. In order to do this change, PWM nodes in board DT files have
been given a pwm{N} label so that both:
- DT API checks such as #if DT_HAS_NODE(DT_NODELABEL(pwmN)) can be
used (N being PWM instance number).
- DT references can be written as pwms = <&pwmN x y>; instead of
pwms = <&{/soc/timers@XXXXXXXX/pwm} x y>;
This approach is also used on the Linux Kernel.

dts pinctrl definitions were pushed in tree without the code
available to deal with it. They have been kept waiting for the
code, but this is taking much more time than initially thought.
So in current zephyr tree, for all STM32 boards, we have pinmux.c
file which is used to configure pins and these files that are
basically no-op. This situation is creating a lot of confusion
especially to new comers, and create useless maintenance effort.
Remove these files for now.
When zephyr will ready to use them, this commit could be reverted.

The DT spec. only has "okay" and not "ok". The Linux kernel has around
12k "okay"s and 300 "ok"s.
The scripts/dts scripts only check for "disabled", so should be safe re.
those at least.
The replacement was done with
git ls-files | xargs sed -i 's/status\s*=\s*"ok"/status = "okay"/'
