perf/x86/intel: Use Intel family macros for core perf events

Use the new model number macros instead of spelling things out
in the comments.

Note that this is missing a Nehalem model that is mentioned in
intel_idle which is fixed up in a later patch.

The resulting binary (arch/x86/events/intel/core.o) is exactly
the same with and without this patch modulo some harmless changes
to restoring %esi in the return path of functions, even those
untouched by this patch.
