The issue here is that we have a handful of options that need converting
still, and are not "easy".  For CONS_INDEX we need to find the right
generic location for this to be and migrate, and remove the few
instances of board-centric versions of the question.

I agree with the sentiment of the original patch but I want to see how
many of the current options can be knocked out easily.  WRT sunxi, I
posted moving two of them, and RGMII will happen as part of the general
move of all of the network drivers over.

SATAPWR and MACPWR will take a little more thinking on, to figure out.
Do these values exist within the normal device tree in some way already
for example?  Thanks!
