This is temporary workaround. Don't merge. See cover-letter
"[PATCH 0/2] ARM: shmobile: sh73a0 Suspend-to-RAM" for more information.

When registering the interrupt handler we add the IRQF_NO_SUSPEND flag
to save the IRQ line from being disabled during suspension. This way we
keep the ability to use the device as a wakeup source.
