Shouldn't there be a driver that acquires the GPIO that's output to the
pin, and configures the output value? IIRC there have been previous
discussions re: having a list of e.g. initial GPIO output values in DT,
and that was rejected, and this patch seems to be doing almost the exact
same thing, just at the pinctrl level rather than GPIO level.

That all said, I admit this could be a useful feature...
