Hmm, that's a nice idea.
Another possibility I was thinking about was adding a gpio number
field to devicetree.cb, so you'd have a flag 'use gpio' and a
register for the gpio number, maybe with negative values meaning
'needs to be inverted' or another flag 'invert gpio', but that
assumes it's always connected to one of the southbridge gpios...
