ARM: mach-shmobile: sh7372 INTCS support
Add support for the sh7372 INTCS interrupt controller. INTCS is the interrupt controller for the sh7372 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.
