[PATCH_V2 23/34] MIPS: jz4740: define IRQ numbers based on number of intc IRQs

[Zubair Lutfullah Kakakhel]

From: Paul Burton <paul.burton@xxxxxxxxxx>

For interrupts numbered after those of the interrupt controller, define
their numbers based upon the number of interrupts provided by the SoC
interrupt controller. This is in preparation for supporting later jz47xx
series SoCs which provide more interrupts.
