KVM: arm64: pmu: Guard PMU emulation definitions with CONFIG_KVM

Browse Source 
Most of the internal definitions for PMU emulation are guarded with
CONFIG_HW_PERF_EVENTS. However, this isn't enough, and leads to
these definitions leaking if CONFIG_KVM isn't enabled.

This leads to some compilation breakage in this exact configuration.
Fix it by falling back to the dummy stubs if either perf or KVM
isn't selected.
