Introduce a new "zephyr,memory-region" compatible to be used when a new
memory region must be created in the linker script from the devicetree
nodes using the compatible.
Remove also the LINKER_DT_REGION_FROM_NODE macro and add a new
LINKER_DT_REGIONS macro to cycle through all the compatible regions.
In the same PR modify the DTS files and the linker scripts.

Certain stm32 soc's have a single shared irq for all adc channels
on those soc's only a single channel is supported.
Added a Kconfig that enables a shared irq for stm32f2x, stm32f4x,
stm32f7x soc's. The shared IRQ uses a flag to limit the number of
interrupts defined to only 1. A shared irq handler is added which
determines which ADC instance the interrupt is for, it then calls
into the existing interrupt.

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.

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.

In STM32 can driver CAN2 instance need to know the base address
of CAN1 instance which is referenced as master can.
Add this information as an optional property to stm32 can binding.

Replace CONFIG_ENTROPY_NAME with DT_CHOSEN_ZEPHYR_ENTROPY_LABEL. We now
set zephyr,entropy in the chosen node of the device tree to the entropy
device.
This allows us to remove CONFIG_ENTROPY_NAME from dts_fixup.h. Also
remove any other stale ENTROPY related defines in dts_fixup.h files.

Convert usb_stm32 driver to use of DT_INST macros.
Since driver is compatible with 3 different dt compatibles and
compatible string is included in DT_INST macros, I've kept the
DT_USB_ compatible agnostic macros based on DT_INST ones, which
allowed to remove fixup definitions.
Use of DT_USB symbols is now limited to usb_dc_stm32.
Additionally, compatible "st,stm32-otgfs" is removed from list
of compatibles for usbotg_hs ips.

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.

We currently get a number of warnings like:
Warning (simple_bus_reg): /soc/otgfs_phy: missing or empty
reg/ranges property
This is due to the usb phy nodes not have a reg property since they
don't have an mmio address associated with them.
Move the phy nodes out of the SoC node so their lack of a reg property
will not cause a warning. This is similar to how Linux dts files
handle the phy nodes.

Add maximum-speed property to usb nodes and set it to

SoCs with USB device controllers only support full

To move forward and remove use of Kconfig in dts files lets just create
