Neel Natu 02904c45ab Hide extended PerfCtr MSRs on AMD processors by clearing bits 23, 24 and 28 in
CPUID.80000001H:ECX.

Handle accesses to PerfCtrX and PerfEvtSelX MSRs by ignoring writes and
returning 0 on reads.

This further reduces the number of unimplemented MSRs hit by a Linux guest
during boot.
