KVM: x86/pmu: Provide Intel PMU's pmc_is_enabled() as generic x86 code
Move the Intel PMU implementation of pmc_is_enabled() to common x86 code
as pmc_is_globally_enabled(), and drop AMD's implementation. AMD PMU
currently supports only v1, and thus not PERF_GLOBAL_CONTROL, thus the
semantics for AMD are unchanged. And when support for AMD PMU v2 comes
along, the common behavior will also Just Work.
