Unify the CAN controller configuration done in Zephyr devicetrees:
- Specify a resynchronization jump width (sjw) of 1 time quanta in SoC
devicetrees as this is the most common. Boards can override this if
needed.
- Specify a sample point of 87.5% as recommended by CAN in Automation
(CiA) in SoC devicetrees. Boards can override this if needed.
- Specify a bus speed of 125 kbits/second (arbitration phase) and 1
Mbits/second (CAN-FD data phase) in board devicetrees as this is what
is used by all Zephyr CAN samples.

Remove the requirement for specifying #address-cells and #size-cells
properties for CAN controller devicetree nodes.
CAN controllers do not have a common concept of devicetree child nodes
and thus have no need for these properties. This is in line with
upstream Linux kernel devicetree bindings.

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)

Property "st,prescaler" of binding "st,stm32-pwm" was set to 2
different default values 0 or 10000 in *.dtsi files.
Since this property rather depends on application than hardware
description, there is no reason to have 2 different default values
in use. Besides, it is a trap for pwm users that should take into
consideration this random default value.
Fix this by defaulting the property systematically to 0.

The device tree includes CAN node can1 for all
STM32L4 chips when in fact they don't all support it.
This affects STM32L412xx and STM32L422xx.

Timer interrupts have been added for all STM32 SoC. H7 series already
had the interrupt definitions. The IRQ number and names have been taken
from the STM32Cube HAL header files.

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

On stm32 spi devices, there are 2 main IP variants, with and w/o
fifo. Fifo is not really used today, but still there is some
additional code handling fifo. Today this code is protected under
Kconfig symbol SPI_STM32_HAS_FIFO.
This code carries redundant information vs dedicated compatible
"st,stm32-spi-fifo", which is provided as unique driver compatible
for devices supporting this IP as opposed to use of "st,stm32-spi"
when fifo is not supported.
Having these 2 compatibles defined exclusively is not convenient for
migration to DT_INST as DT_INST macros contain compatible string and
hence it cannot be used to provide common compatible code for devices
defining different compatibles.
Based on these observations, review stm32 spi devices compatible
declarations. Devices supporting fifo will now declare both
compatibles, as proposed by dt spec: "[compatible] property value
consists of a concatenated list of null terminated strings,
from most specific to most general". Hence field will now be:
"st,stm32-spi-fifo", "st,stm32-spi"
This way, fifo enabled stm32 spi devices will generate both:
DT_INST_STM32_SPI_FOO and DT_INST_STM32_SPI_FIFO_FOO
As well as:
DT_COMPAT_ST_STM32_SPI and DT_COMPAT_ST_STM32_SPI_FIFO
So, DT_INST_STM32_SPI_FOO could be used for device initialization.
Also DT_COMPAT_ST_STM32_SPI_FIFO could be used for FIFO handling
code inside driver. Hence use it to replace Kconfig symbol
SPI_STM32_HAS_FIFO.
