sh: multiple vectors per irq - sh7750
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 sh775x hardware blocks such as SCI/SCIF/RTC/DMAC/TMU2/REF. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
