[PATCH] ARM: OMAP2: twl-common: Fix compiler warning

[tony@atomide.com (Tony Lindgren)]

* Peter Ujfalusi <peter.ujfalusi@ti.com> [120615 06:38]:
> If the kernel is built only for OMAP2 the following warning will show up:
> 
> arch/arm/mach-omap2/twl-common.c:52: warning: ?twl_set_voltage? defined but not used
> arch/arm/mach-omap2/twl-common.c:58: warning: ?twl_get_voltage? defined but not used
> 
> The twl_set/get_voltage callbacks only used when OMAP3/4 is selected.

Thanks applying into fixes.
