Ard Biesheuvel c722289324 ArmPkg/ArmLib: move cache maintenance sync barriers out of loop
There is no need to issue a full data synchronization barrier and an
instruction synchronization barrier after each and every set/way or
MVA cache maintenance operation. For the set/way case, we can simply
remove them, since the set/way outer loop already issues the required
barriers after completing its traversal over all the cache levels.

For the MVA case, move the data synchronization barrier out of the
loop, and add the instruction synchronization barrier to the I-cache
invalidation by MVA routine.
