Allow regulator nodes to hold their own init data

Unfortunately due to a rather large testing oversight on my part the recently merged Lochnagar regulator binding does not actually work. The binding looks like this:

lochnagar {
        compatible = "cirrus,lochnagar1";

        ...

        lochnagar-micvdd: MICVDD {
                compatible = "cirrus,lochnagar2-micvdd";

                SYSVDD-supply = <&wallvdd>;

                regulator-min-microvolt = <3300000>;
                regulator-max-microvolt = <3300000>;
        };
        lochnagar-vddcore: VDDCORE {
                compatible = "cirrus,lochnagar2-vddcore";

                SYSVDD-supply = <&wallvdd>;

                regulator-min-microvolt = <1200000>;
                regulator-max-microvolt = <1200000>;
        };
};

The trouble is that each regulator node individually binds in a driver and contains the init data. The regulator core appears to require the init data to be a sub-node of the node that bound in the regulator driver. As the above binding seems reasonable I opted to try and update the core to support the current binding, although as the rest of the Lochnagar driver isn't merged yet we could still update the binding if that comes out of the review as a preferred option. Apologies for missing such a glaring issue in my testing.

Thanks,
Charles
