13  C-SKY Multi-processors Interrupt Controller is designed for ck807/ck810/ck860
14  SMP soc, and it also could be used in non-SMP system.

16  Interrupt number definition:
17    0-15  : software irq, and we use 15 as our IPI_IRQ.
18    16-31  : private  irq, and we use 16 as the co-processor timer.
19    31-1024: common irq for soc ip.
