Magnus Damm 0e9131a3fa 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.
