Subject: [PATCH 07/29] perf hists: Make hpp setup function generic

From: Jiri Olsa <jolsa@...nel.org>

Now that we have the 'equal' method implemented for hpp format entries
we can ease up the logic in the following functions and make them
generic wrt comparing format entries:

  perf_hpp__setup_output_field
  perf_hpp__append_sort_keys
