Microchip AT91 fixes for v6.17

Browse source 
This update includes:
 - adaptation to the SDHCI capabilities on sama7d65 curiosity board DT as
   SDHCI quirks are not in place yet. SD/MMC don't work without these
 - addition of one Kconfig symbol that is already used in DMA tree for
   6.17. XDMA cannot be selected if not present.
