checks: add phandle with arg property checks

Browse source 
Many common bindings follow the same pattern of client properties
containing a phandle and N arg cells where N is defined in the provider
with a '#<specifier>-cells' property such as:

	intc0: interrupt-controller@0 {
		#interrupt-cells = <3>;
	};
	intc1: interrupt-controller@1 {
		#interrupt-cells = <2>;
	};

	node {
		interrupts-extended = <&intc0 1 2 3>, <&intc1 4 5>;
	};

Add checks for properties following this pattern.
