In some stm32 series systick was disabled in order to
allow alternate use of lptim timer as kernel low power ticker.
Doing this, dts based definition of CORTEX_M_SYSTICK Kconfig symbol
is disabled and CORTEX_M_SYSTICK was redefined with 'default y'
in stm32 soc files which makes things more complex to handle to
alternate with LPTIM activation.

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.

2 versions of DMA hardware blocks could be found across stm32 series.
In order to simplify the handling of matching Kconfig symbols,
make this visible in dts files by creating "st,stm32-dma-v1" and
"st,stm32-dma-v2" and set them accordingly in dtsi files.
Duplicate and update related bindings to reflect that new state.

Change #28199 introduced systick configuration from device tree.
For now this should not be used on platforms that support alternate
tick source, as this is the case on l4 and wb series with LPTIM.
Until dts allows to configure lptim from dts, keep systick disabled
by default on these platforms.
Fixes#28280

Replace DT_FLASH_DEV_NAME with DT_CHOSEN_ZEPHYR_FLASH_CONTROLLER_LABEL.
We now set zephyr,flash-controller in the chosen node of the device
tree to the flash controller device.
NOTE: For a SoCs with on die flash, this points to the controller and
not the 'soc-nv-flash' node. Typically the controller is the
parent of the 'soc-nv-flash' node).

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.

stm32wb55rg is a dual core SoC (M4/M0) with a radio/protocol stack
running on M0 core. M0 FW starts at flash address 0x80CB000.
So flash size available to zephyr is 812K instead of 1M.
Configure package size to reflect this (flash size is now 812K)
and update MPU setting to exclude M0 FW. From MPU point of view,
we set flash size to 512K since we should chose a size being a power
of 2.
If we consider there will be 2 images partitions in a FOTA scheme,
512 K is beyond image-0 and hence is sufficient to cover application
image.
