KVM: x86/pmu: Apply "fast" RDPMC only to Intel PMUs
Move the handling of "fast" RDPMC instructions, which drop bits 63:32 of
the count, to Intel. The "fast" flag, and all modifiers for that matter,
are Intel-only and aren't supported by AMD.
Opportunistically replace open coded bit crud with proper #defines, and
add comments to try and disentangle the flags vs. values mess for
non-architectural vs. architectural PMUs.
