[PATCH] Don't mask rtc-twl4030 alarm interrupts on shutdown

[PATCH] Don't mask rtc-twl4030 alarm interrupts on shutdown

[matti.halme]

A triggering RTC alarm should be able to power on a device that has been
powered off. This patch enables that on twl4030 by not masking the alarm
interrupt at shutdown.

Looks like this is already queued up for mainline by Alessandro,
so pushing to linux-omap tree while waiting for it to fall down
from mainline.
