This commit set the stm32 octospi drivers for the stm32u5x
when DMA (GPDMA) is transferring.
Valid for octospi1 or octospi2.

Introducing the dma transfer (also through dmamux)
to transfer data to/from the NOR octo-flash
With a DMAMUX, the DMA channel is given by the DTS.
Note that STM32U5X does not support DMA here.

Update flash drivers to use DT_HAS_<compat>_ENABLED Kconfig symbol
to expose the driver and enable it by default based on devicetree.
We remove 'depend on' Kconfig for symbols that would be implied by
the devicetree node existing.

This is the stm32 octospi driver based on the exisitng quadspi
for stm32 devices and source code from the STM32Cube.
This drivers initialized the peripheral and the NOR memory
in SPI or OctoSPI mode with STR or DTR data Transfer rates.
The NOR-flash can provide the SDFP table directly (if supported)
or through the DeviceTree.
Limitation: no DMA transfer.
