Not quite sure whether regulator would be right fit for this.

Initially I was thinking of making use of pinconf framework, using
PIN_CONFIG_POWER_SOURCE, but that too I am not sure is the right way of
doing it.

Probably, question for pinctrl maintainer. Looping Linus Walleji.

We have another pinctrl driver exposing the occasional fixed regulator
for exactly this purpose, see:
sh-pfc/pfc-sh73a0.c

So use the same mechanism for this driver.
