Silicon/Socionext/SynQuacer: add configurable eMMC support

Implement support for the SynQuacer eMMC controller. This involves an
implementation of the SD/MMC override protocol to handle a couple of
quirks that would otherwise prevent this IP from being driven by the
generic SDHCI driver.

Also, add a HII page to the PlatformDxe driver that allows eMMC support
to be enabled, and wire it up for both DeveloperBox and EVB.
