Hao Wu 85ad9a6e0a MdeModulePkg/EmmcBlockIoPei: Support IoMmu
Update the EmmcBlockIoPei driver to consume IOMMU_PPI to allocate DMA
buffer.

If no IOMMU_PPI exists, this driver still calls PEI service
to allocate DMA buffer, with assumption that DRAM==DMA.

This is a compatible change.

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
