Microchip AT91 fixes for v6.17

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.
