perf/x86/intel: Decouple BTS initialization from PEBS initialization

Browse source

Move x86_pmu.bts flag initialization into bts_init() from
intel_ds_init() and rename intel_ds_init() to intel_pebs_init() since it
fully initializes PEBS now after removing the x86_pmu.bts
initialization.

It's safe to move x86_pmu.bts into bts_init() since all x86_pmu.bts flag
are called after bts_init() execution.
