Stephane noticed that the ANY flag was in generic arch code, and Cyrill
reported that it broke the P4 code.

Solve this by merging x86_pmu::raw_event into x86_pmu::hw_config and
provide intel_pmu and amd_pmu specific versions of this callback.

The intel_pmu one deals with the ANY flag, the amd_pmu adds the few extra
event bits AMD64 has.
