A few files now need to include linux/io.h directly, which used to be included through other headers that have changed. The new at91_aic_irq_priorities variable is only used with CONFIG_OF enabled and should not be visible otherwise.

If this happens, the RTC alarm should trigger a wakeup event, possibly aborting system suspend. This condition can be detected in the form of an RTC alarm interrupt.
