Thx Kelley/Reding for comments,
Yes, the vxd392 is a totally different IP and it also exist on Intel's non-GEN platforms such as Merrifield. If we put it inside i915 there'll be issue if we someday supports Merrifield.

It is an entirely unrelated HW IP block, VXD392. Nothing to do with GEN aside from DRM based.
