[PATCH 11/15] ARM: OMAP: timer: Interchange clksrc and clkevt for AM33XX

AM33XX has only one usable timer in the WKUP domain.
Currently the timer instance in WKUP domain is used
as the clockevent and the timer in non-WKUP domain
as the clocksource. The timer in WKUP domain can keep
running in suspend from a 32K clock and hence serve
as the persistent clock. To enable this, interchange
the timers used as clocksource and clockevent for
AM33XX. A subsequent patch will add suspend-resume
support for the clockevent to ensure that there are
no issues with timekeeping.
