Register sub devices of the PMC to support multiple functionalities

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.
Since I don't think anyone has mentioned this point on the public lists,
I'll echo the earlier internal discussion on this patch. I think the PMC
driver should handle this all entirely internally. The PMC HW module
doesn't have well-defined sub-modules, and hence we shouldn't represent
sub-modules in DT. DT should represent HW structure, not Linux SW structure.
