sh: multiple vectors per irq - sh7763

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 sh7763 hardware
blocks such as RTC/SCIF/DMAC/GETHER/PCIC5/MMCIF/SIM/GPIO/USBF.
