RTC: Convert rtc drivers to use the alarm_irq_enable method
Some rtc drivers use the ioctl method instead of the alarm_irq_enable
method for enabling alarm interupts. With the new virtualized RTC
rework, its important for drivers to use the alarm_irq_enable instead.
This patch converts the drivers that use the AIE ioctl method to
use the alarm_irq_enable method. Other ioctl cmds are left untouched.
I have not been able to test or even compile most of these drivers.
Any help to make sure this change is correct would be appreciated!
