clocksource/drivers/timer-ti-dm: Do one override clock parent in prepare()

omap_dm_timer_prepare() is setting up the parent 32KHz clock. This
prepare() gets called by request_timer in the client's driver. Because of
this, the timer clock parent that is set with assigned-clock-parent is being
overwritten. So drop this default setting of parent in prepare().
