KVM: arm64: Add missing reset handlers for PMU emulation

As we're about to become a bit more harsh when it comes to the lack of
reset callbacks, let's add the missing PMU reset handlers. Note that
these only cover *CLR registers that were always covered by their *SET
counterpart, so there is no semantic change here.
