sh: multiple vectors per irq - sh7780

Update intc tables and platform data to use one linux irq
per maskable interrupt source instead of keeping the one-to-one
mapping between vectors and linux irqs.

This fixes potential irq masking issues for sh7780 hardware
blocks such as SCIF/RTC/DMAC/PCIC5/MMCIF/FLCTL/GPIO
