That's missing the point. Regulators are superior if there is
controlling driver. E.g.
https://www.kernel.org/doc/Documentation/devicetree/bindings/usb/usb-nop-xceiv.txt

See arch/arm/boot/dts/armada-385-linksys.dtsi for a nice, OpenWrt
relevant, example using this with a fixed regulator.

If you don't link anything to the regulator, then I agree that you might
as well use gpio-hog.  But I still don't see how you can call that a
superior solution.  It doesn't suck more or less.  I thought the ath79
conversion was all about using devicetree to document the boards ;-)
