Now it implements SdMmcOverride protocol which allows to add quirks to the generic SdMmcPciHcDxe. Platforms that were using XenonDxe/SdMmcPciHcDxe have fixed *.fdf and *.dsc.inc files to use new implementation of XenonDxe. In the new version of the driver apart from using SdMmcOverride protocol, this patch utilizes newly added controllers' description in MvBoardDesc protocol, as well as improved PHY configuration sequence.
