KVM: arm64: Only apply PMCR_EL0.P to the guest range of counters
An important distinction from other registers affected by HPMN is that
PMCR_EL0 only affects the guest range of counters, regardless of the EL
from which it is accessed. Ensure that PMCR_EL0.P is always applied to
'guest' counters by manually computing the mask rather than deriving it
from the current context.
