It isn't obvious in the current devicetree what is connected. Go ahead
and document what's on the other end.

Not sure if this sort of patch is actually welcomed or not but I went
through this exercise (for the prior patch) and thought it might be
useful to document.
Shazad, this also highlights (unless I misread things) that i2c12 has no
use for us, right? If agreed I can remove it but sorting through the
lore links that provided all this it seems like at the time it was
desired to be added.
Thanks,
Andrew
