Register sub devices of the PMC to support multiple functionalities
of PMC.
The sub devices are the subnode of PMC DT node with containing the
compatible string of sub devices as follows:

        pmc@0,7000e400 {
		pmc-pad-control {
			compatible = "nvidia,tegra210-io-pad";
			::
		};
	};

In this pmc-pad-control is the sub device of PMC and the device
compatibility is nvidia,tegra210-io-pad.
