Convert from device_get_binding to DEVICE_DT_GET. In doing this we
no longer need the label in the devicetree node so we remove that.
Removed all __ASSERT_NO_MSG(clk) since we'll get a build error if
DEVICE_DT_GET cant be satisfied, and the clock control api's will
handle reporting if the device_is_ready.

Rename compatible st,stm32-pinmux to st,stm32-pinctrl to better
reflect the nature of upcoming child nodes.

For true mmio-sram, arc,iccm, arc,dccm nodes we should not be setting
device_type = "memory". This should be used for true DRAM regions of
memory and not on SoC SRAMs.

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

64 kB of memory is reserved for the inter-processor
communication. this makes sense only if RPMsg is used.
Allow to use this memory for firmware data by default.

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.

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.

Implementation of pinmux for the stm32mp157c_dk2 board.
Some UART pin mux definition has been added (mainly for
UART console and UART/SPI Arduino shield support).
This can be completed with pin mux for other stm32mp157c
UART.
