MdeModulePkg/UfsPassThruDxe: Refactor private data to use UfsHcInfo

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

Private data has been refactored to use EDKII_UFS_HC_INFO structure
to store host controller capabilities and version
information. Getting host controller data has been moved
into single place and is done before host controller enable.
