Enable DMA support mainly for stm32U5 family.
It differs from the DMA driver due to the GPDMA peripheral.

Enable DMA V2 or DMA V2bis support. With the versions V2 of DMA, the
peripheral request must be specified in the dma slot of the dma cell
With the versions V2 bis of DMA, the peripheral request (slot) is not
a parameter of the dma-cell.

DMAMUX driver device must be init'd after the DMA (CONFIG_DMA_INIT_PRIORITY)
DMAMUX driver device initialization priority is greater than DMA one's
