I guess I was looking at the VBT changes in intel_bios.c. Granted, they
do end up being used as i2c addresses. No big deal.

I think I'd expect the treewide i2c adapter changes to land first, via
i2c, and subsequent cleanups to happen next, via individual driver
trees. There's quite a bit of conflict potential merging this outside of
drm-intel-next, and there's really no need for that.
