Add a stm32 compatible driver for MSPI controllers based on stm32 XSPI peripheral. Signed-off-by: Francois Ramu <[email protected]>
Introduce a stm32 MSPI controller driver based on the xspi peripheral of stm32 mcus. A new CONFIG_MSPI_STM32 is defined for this. Supports SPI/OPI and STR (DTR mode is not supported yet). Signed-off-by: Francois Ramu <[email protected]>
Declare the xspi node of the stm32h573i_dk node to be MSPI "st,stm32-mspi-controller"compatible when running the samples/drivers/mspi/ Signed-off-by: Francois Ramu <[email protected]>

This PR is introducing the stm32 MSPI controller driver for stm32 series.
On the stm32h573i_dk disco kit where the external flash is the mx25lm51245 ; "jedec,mspi-nor" compatible
the mspi node is the xspi instance which is "st,stm32-mspi-controller"; compatible
--> new version of the #78186
Using the samples/drivers/mspi/mspi_flash to test the access to the stm32 MSPi controller
with an overlay file taht can re-define the xspi1 node to be "st,stm32-mspi-controller" compatible. That will avoid disturbing existing stm32h562 and stm32h573 board configuration (DTSi unchanged)
