[PATCH 4.4 100/268] ARM: OMAP: Fix dmtimer init for omap1

[Greg Kroah-Hartman]

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Tony Lindgren <tony@xxxxxxxxxxx>

[ Upstream commit ba6887836178d43b3665b9da075c2c5dfe1d207c ]

We need to enable PM runtime on omap1 also as otherwise we
will get errors:

omap_timer omap_timer.1: omap_dm_timer_probe: pm_runtime_get_sync failed!
omap_timer: probe of omap_timer.1 failed with error -13
...

We are checking for OMAP_TIMER_NEEDS_RESET flag elsewhere so this is
safe to do.
