omap: timer: Set dmtimer used as clocksource in autoreload mode
If CONFIG_OMAP_32K_TIMER is not selected and dmtimer is used as clocksource, the
timer stops counting once overflow occurs as it was not set in autoreload mode.
This results into timekeeping failure: for example, 'sleep 1' at the shell after
the timer counter overflow would hang.
This patch sets up autoreload when starting the clocksource timer which fixes
the above issue.
