KVM: x86/pmu: Introduce distinct macros for GP/fixed counter max number
Refine the macros which define maximum General Purpose (GP) and fixed counter numbers. Currently the macro KVM_INTEL_PMC_MAX_GENERIC is used to represent the maximum supported General Purpose (GP) counter number ambiguously across Intel and AMD platforms. This would cause issues if AMD begins to support more GP counters than Intel. Thus a bunch of new macros including vendor specific and vendor independent are introduced to replace the old macros. The vendor independent macros are used in x86 common code to hide vendor difference and eliminate the ambiguity. No logic changes are introduced in this patch.
