target/ppc: PMU: update counters on PMCs r/w
Calling pmu_update_cycles() on every PMC read/write operation ensures
that the values being fetched are up to date with the current PMU state.
In theory we can get away by just trapping PMCs reads, but we're going
to trap PMC writes to deal with counter overflow logic later on. Let's
put the required wiring for that and make our lives a bit easier in the
next patches.
