perf_counter, x86: rework counter enable functions
There is vendor specific code in generic x86 code, and there is vendor
specific code that could be generic. This patch introduces
x86_pmu_enable_counter() for x86 generic code. Fixed counter code for
Intel is moved to Intel only functions. In the end, checks and calls
via function pointers were reduced to the necessary. Also, the
internal function i/f changed.
[ Impact: refactor and generalize code ]
