drivers/rtc/rtc-omap.c: enable RTC_IRQWAKEEN bits when Alarm is set
When RTC CLKTRCTRL bit is configured in HW_AUTO, module goes to sleep in
IDLE state.
The Alarm SWakeup event can be used to wakeup the RTC when it is in IDLE
state. In order to do so, the alarm needs to be set and enabled before
RTC enters the IDLE state. Also the wakeup generation for alarm/timer
event needs to be set (bits [1:0] in RTC_IRQWAKEEN register).
Currently RTC_IRQWAKEEN bits are set only in suspend/resume paths. With
this ALARM interrupts are not generated when it enters IDLE state. So
programming the RTC_IRQWAKEEN bits when ever ALARM is set.
