MIPS: JZ4740: define IRQ numbers based on number of intc IRQs
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 newer Ingenic SoCs which provide more interrupts.
