[PATCH v3 1/6] dt-bindings: interrupt-controller: Refine size/interrupt-cell usage.

[Kevin Chen]

1. Because size-cells is no need to use 2, modify to 1 for use.
2. Add minItems to 1 for interrupts for intc1.
3. Add 1 interrupt of intc1 example into yaml file.
4. Add intc1 sub-module of uart12 as example using the intc0 and intc1.
