Add the pinctrl state name (default) for the UART/USART/LPUART
peripherals. Changes performed using the following Python script run
from the repository root:
```
from pathlib import Path
import re
for fpath in Path(".").glob("boards/arm/**/*.dts"):
lines = open(fpath).readlines()
is_stm32 = False
for line in lines:
if "stm32" in line:
is_stm32 = True
break
if not is_stm32:
continue
with open(fpath, "w") as f:
for line in lines:
f.write(line)
m = re.match(r"(\s+)pinctrl-0.*us?art.*", line)
if m:
f.write(m.group(1) + "pinctrl-names = \"default\";\n")
```

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)

Update PWM pinctrl signal names of all non-F1 STM32 boards.
`pwm` variant is not available anymore on non-F1 series.

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.

Use the new DT facilities to configure PWM pinmux on NUCLEO-L496ZG
board.
NOTE: pwm4 node has been deleted as it was not actually used nor
documented.

Add support for the polarity flag in the STM32 PWM driver.
STM32 boards using PWM have been updated accordingly.

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"/'

Supported PWM at pins A0, D3, D5 and D6 which are also Arduino
compatible. Also the onboard red LED can be used with PWM.
The basic/{fade_led, blink_led} samples to apply to this board
seemlessly and operate on the onboard red LED.
Also supported RTC.
