Browse Source 
The functions that are never called have been removed.
They are UfsPeimUnlinkMemBlock,UfsPeimRequestSense,
UfsPeimInquiry,UfsRwAttributes,UfsClearFlag,UfsReadFlag
and UfsFindAvailableSlotInTmrl.
https://bugzilla.tianocore.org/show_bug.cgi?id=1062

v2: Remove the comment that mentioned 'UfsPeimUnlinkMemBlock'
within function UfsPeimFreeMemPool().
