[PATCH] dt-bindings: interrupt-controller: Convert csky,mpintc to DT schema

[PATCH] dt-bindings: interrupt-controller: Convert csky,mpintc to DT schema

[Rob Herring (Arm)]

Convert the C-SKY Multi-processor interrupt controller binding to schema
format. It's a straight-forward conversion of the typical interrupt
controller.

-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.
-
-Interrupt trigger mode: (Defined in dt-bindings/interrupt-controller/irq.h)
- IRQ_TYPE_LEVEL_HIGH (default)
- IRQ_TYPE_LEVEL_LOW
- IRQ_TYPE_EDGE_RISING
- IRQ_TYPE_EDGE_FALLING
