ARM: mach-shmobile: sh7367 INTCS support
Add support for the sh7367 INTCS interrupt controller. INTCS is the interrupt controller for the sh7367 SuperH processor core. It is tied into the INTCA interrupt controller which interfaces to the ARM processor. INTCS support is implemented using a new INTC table together with a chained interrupt handler that ties into the already supported INTCA controller.
