sh: oprofile: Use perf-events oprofile backend
Now that we've got a generic perf-events based oprofile backend we might as well make use of it seeing as SH doesn't do anything special with its oprofile backend. Also introduce a new CONFIG_HW_PERF_EVENTS symbol so that we can fallback to using the timer interrupt for oprofile if the CPU doesn't support perf events. Also, to avoid a section mismatch warning we need to annotate oprofile_arch_exit() with an __exit marker.
