The old dts file specified completely the wrong regulator.  It
happened that the old code didn't really care, but when the code was
fixed to care then things broke.  If we need to keep old dts files
working then the most sensible place to do it would be in a "fixup old
broken device trees" stage somewhere in kernel boot.
