MIPS: Loongson64: Adjust IRQ layout
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.
