This shouldn't be inside the SoC node because it doesn't have a reg
property. It should be in a 'regulators' node that's in the root of the
tree:

regulators {
compatible = "simple-bus";

ext_3p3v: fixedregulator@0 {
compatible = "regulator-fixed";
...
};
};

This should be done via the *-gpios method. i.e. hdmi-tx-ddc-clk-gpios,
hdmi-tx-ddc-data-gpios, etc.

This should be an OPP.
