Marc Zyngier 11af4c3716 KVM: arm64: PMU: Implement PMUv3p5 long counter support 
PMUv3p5 (which is mandatory with ARMv8.5) comes with some extra
features:

- All counters are 64bit

- The overflow point is controlled by the PMCR_EL0.LP bit

Add the required checks in the helpers that control counter
width and overflow, as well as the sysreg handling for the LP
bit. A new kvm_pmu_is_3p5() helper makes it easy to spot the
PMUv3p5 specific handling.
