[PATCH 25/26] ARM: OMAP: dmtimer: Eliminate omap_dm_timer_int_enable function

From: Joel Fernandes
Date: Thu Apr 24 2014 - 18:46:34 EST


Fold this function back into omap_dm_timer_set_int_enable and
use the systimer flag to not call PM functions for system timer.
Then remove it from the header file, and convert users to use
omap_dm_timer_set_int_enable.
