Add INTCS support to the sh7367 INTC code. The INTCS block
is a separate interrupts controller shared with the sh4 core
which hangs off the INTCA interrupt controller.

Needs the INTC ioremap patch.

* [PATCH] 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.
