[PATCH v2] hw_breakpoint: Let the user choose not to build it (and perf too)

[Frederic Weisbecker]

Mostly just a rebase against latest upstream
updates and acks from Will Deacon added In this second version.

Please tell me if you are ok with this set.

Thanks.

Frederic Weisbecker (6):
      hw_breakpoints: Split hardware breakpoints config
      hw_breakpoints: Migrate breakpoint conditional build under new config
      x86: Allow the user not to build hw_breakpoints
      hw_breakpoints: Breakpoints arch ability don't need perf events
      hw_breakpoints: Only force perf events if breakpoints are selected
      hw_breakpoints: Drop remaining misplaced dependency on perf
