linux/arch/arm/mach-shmobile/intc-r8a7740.c
Kuninori Morimoto 215d6cc923 ARM: mach-shmobile: r8a7740: add INTC support 
R8A7740 GIC can not get external IRQx interrupt directly
without GIC - INTC demux support.

Current AG5 is using GIC - INTCS demux with
special irq relocation. but GIC - INTCA demux
is still not supported and it needs irq number re-mapping.

OTOH, normal INTC support as before is very enough for R8A7740,
because it is not SMP CPU.
This patch adds INTCA/INTCS support instead of GIC.
