MdeModulePkg/SdMmcPciHcDxe: Using PIO rather than DMA for clock tuning
The original code is using ADMA mode to do clock tuning procedure. It
may have problem on some SD/MMC host controllers as there is no way to
know when to send next tuning cmd.
Update it to PIO mode to strictly follow SD Host Controller Simplified
Specification 3.0 Figure 2-29. By this way, if the Buffer Read Ready
interrupt is set, we could know it's ok to send the next clock tuning
cmd.

MdeModulePkg/SdMmcPciHcDxe: Use BaseClk if the target clock is larger
The original code has a bug to calculate which clock freq should be
used when the target clock freq is larger than the BaseClock Freq
provided by the system.

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.
