===========================================
C-SKY Multi-processors Interrupt Controller
===========================================
C-SKY Multi-processors Interrupt Controller is designed for ck807/ck810/ck860
SMP soc, and it also could be used in non-SMP system.
Interrupt number definition:
0-15 : software irq, and we use 15 as our IPI_IRQ.
16-31 : private irq, and we use 16 as the co-processor timer.
31-1024: common irq for soc ip.
=============================
intc node bindings definition
