Pull out ASIC revision from HSA capability

KFD now passes the ASIC revision to user level through some bits
in the HSA topology's capability field. Some user-level software
wants this because different ASIC revisions may require user-level
software to do different things (e.g. patch code for things that
are changed in later hardware revisions).
