KVM: arm64: PMU: Move the ID_AA64DFR0_EL1.PMUver limit to VM creation

As further patches will enable the selection of a PMU revision
from userspace, sample the supported PMU revision at VM creation
time, rather than building each time the ID_AA64DFR0_EL1 register
is accessed.

This shouldn't result in any change in behaviour.
