Currently, arch-mmp/time.c uses timer 0 both as a clocksource timer and as a clockevent timer, the latter by setting up a comparator interrupt to match on 'current_time + delta'. This is problematic if delta is small enough, as that can lead to 'current_time + delta' already being in the past when comparator setup has finished, leading to the requested event not triggering. As there is also a silicon issue that requires stopping a timer's counter while writing to one of its match registers, we'll switch to using two separate timers -- timer 0 as clockevent timer, which we'll start and stop on every invocation of ->set_next_event(), and timer 1 as clocksource timer, which will be free-running. This first patch enables timer 1 on boot, so that we can use it as clocksource timer.
