MdeModulePkg/SdMmc: Add EDKII SD/MMC stack
This stack includes:
1. Dxe phase support by:
1) SdMmcPciHcDxe driver to consume PciIo and produce
SdMmcPassThru.
2) SdDxe driver to consume SdMmcPassThru to produce
BlkIo1/BlkIo2.
3) EmmcDxe driver to consume SdMmcPassThru to produce
BlkIo1/BlkIo2/SSP.
2. Pei phase support
1) SdBlockIoPei driver to consume SdMmcHostController
Ppi and produce VirutalBlkIo1&2.
2) EmmcBlockIoPei driver to consume SdMmcHostController
Ppi and produce VirutalBlkIo1&2.
3) SdMmcPciHcPei driver to produce SdMmcHostController
Ppi.
