KVM: arm64: Add {get,set}_user for PM{C,I}NTEN{SET,CLR}, PMOVS{SET,CLR}
For unimplemented counters, the bits in PM{C,I}NTEN{SET,CLR} and
PMOVS{SET,CLR} registers are expected to RAZ. To honor this,
explicitly implement the {get,set}_user functions for these
registers to mask out unimplemented counters for userspace reads
and writes.
