Marc Zyngier c82d28cbf1 KVM: arm64: PMU: Distinguish between 64bit counter and 64bit overflow
The PMU architecture makes a subtle difference between a 64bit
counter and a counter that has a 64bit overflow. This is for example
the case of the cycle counter, which can generate an overflow on
a 32bit boundary if PMCR_EL0.LC==0 despite the accumulation being
done on 64 bits.

Use this distinction in the few cases where it matters in the code,
as we will reuse this with PMUv3p5 long counters.
