KVM: arm64: Use KVM_REQ_RELOAD_PMU to handle PMCR_EL0.E change

Browse source

Nested virt introduces yet another set of 'global' knobs for controlling
event counters that are reserved for EL2 (i.e. >= HPMN). Get ready to
share some plumbing with the NV controls by offloading counter
reprogramming to KVM_REQ_RELOAD_PMU.
