Adjust IRQ layout in order to use IRQ resources more efficiently, which is done by adjusting NR_IRQS and MIPS_CPU_IRQ_BASE. Before this patch: 0~15: ISA/LPC IRQs; 16~55: Dynamic IRQs; 56~63: MIPS CPU IRQs; 64~127: PCH IRQs; 128~255: Dynamic IRQs. After this patch: 0~15: ISA/LPC IRQs; 16~23: MIPS CPU IRQs; 24~87: PCH IRQs; 88~280: Dynamic IRQs.
