Subject: [PATCH] dt-bindings: irqchip: Add node name to PRUSS INTC

The current PRUSS Interrupt Controller binding doesn't exactly specify
the convention for the node name. These interrupt-controllers will always
have a unit address. Update the binding with the '$nodename' using the
expected generic name, this shall ensure the interrupt-controller.yaml
is automatically applied to this binding.
