ARM: mach-shmobile: sh73a0 GPIO IRQ support
This patch adds support for sh73a0 GPIO IRQs by making use of the PFC GPIO IRQ feature. Only IRQ pins are supported at this time. In the future when PINT interrupts also are supported properly we can easily extend the table with such information. Also, the sh73a0 is currently making use of the GIC for external interrupt which is rather unflexible when it comes to triggering configuration at this point.
