Eric Auger a17d216404 KVM: arm64: pmu: Fix chained SW_INCR counters
commit aa76829171 upstream.

At the moment a SW_INCR counter always overflows on 32-bit
boundary, independently on whether the n+1th counter is
programmed as CHAIN.

Check whether the SW_INCR counter is a 64b counter and if so,
implement the 64b logic.

Fixes: 80f393a23b ("KVM: arm/arm64: Support chained PMU counters")
