[PATCH 2/2] MdeModulePkg/SdMmcPciHcDxe: Allow additional SDHCI versions

[Jeff Brasen <jbrasen@nvidia.com>]

Clock control is similar in SDHCI versions greater then version 3. Add
support for more recent versions of the controller specification.

SD card support for 1.8V is also present in controller versions 3 and
greater.
