Probably would be best just to have everything in northbridge/cx700, to
avoid any confusion. Either that, or we can probably hack the vt8237r
code to make it work for both, so there's not two separate sets of
nearly identical code.

Yeah, seems that way. The device IDs are almost all CN700/VT8237R +
0010. We'll know a lot more once we get working on this, and also once I
get the CN700 docs (which I'm still waiting on Via on, deadline's been
pushed back thankfully, but I'm still desperate for 'em).

Good to hear!
