To work efficiently, SPI_NSS pins require pull-up configuration.
Fix this for whole STM32 series.

Fixes#16739. Changed the STM32's SPI MISO/MOSI configurations in order
to reduce the power consumption by approximately 20uA per pin.
According to STM32's Application Notes on GPIO configuration for
low-power consumption, the input pins should be configured with internal
pull-up or pull-down resistor. If a pin is configured as a floating
input, and there is no signal present, the Schmitt trigger randomly
toggles between the logical levels induced by the external noise, thus
increasing the consumption.

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.

STM32L4 pinmux handler is reworked to support future pinmux dts
generation.
Preliminary change is done to move pin configuration
informations in a {pin, conf} structure closer to dts fields
"pins" array is removed and information is transferred to
"pinconf" array

For a better clarity and minimize the possibility
of false definitions and duplicates, gather defines
by port and store the by alphabetical order then in
alternate function order.

Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.
Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.
Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file. Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.
