ARM: 6073/1: oprofile: remove old files and update KConfig

Enable hardware perf-events if CPU_HAS_PMU and select
HAVE_OPROFILE if HAVE_PERF_EVENTS. If no hardware support
is present, OProfile will fall back to timer mode.

This patch also removes the old OProfile drivers in favour
of the code implemented by perf.
