perf map: Add helper for ->map_ip() and ->unmap_ip()

Browse Source 
Later changes will add reference count checking for struct map, add a
helper function to invoke the map_ip and unmap_ip function pointers. The
helper allows the reference count check to be in fewer places.

Committer notes:

Add missing conversions to:

  tools/perf/util/map.c
  tools/perf/util/cs-etm.c
  tools/perf/util/annotate.c
  tools/perf/arch/powerpc/util/sym-handling.c
