The regulator core register the regulator even if there is NULL

registration to fail.
So providing the dec->supply_name only in case of valid init_data.
This works fine if you have a device per regulator instead of a device
for all the regulators on the chip... I would be inclined to address
this by providing a "floating" supply and connecting everythinng to
I am fine with adding floating supply similar to below and connect all non-connected supply pins to this.

floating: regulator@1 {
compatible = "regulator-fixed";
reg = <1>;
regulator-name = "floating";

If this is fine then I will respin the patch to remove condition.
