MdeModulePkg/UfsPassThruDxe: Implement EDKII_UFS_HC_PLATFORM_PROTOCOL

Browse Source 
https://bugzilla.tianocore.org/show_bug.cgi?id=1343

This commit adds EDKII_UFS_HC_PLATFORM_PROTOCOL implementation
in UfsPassThruDxe driver in version 1. Driver assumes that at
most one instance of the protocol exists in the system. Presence
of the protocol is not mandatory.
