I'd really like to keep the pipe C limitation in the gen9 block, but yes, it was
missing GLK. (Patches were originally written before GLK, I believe) Thanks for
catching that.
I really suspect we're going to need to split display version out of INTEL_GEN.
Maybe you guys are already doing this.
I'm fine with ccs rename, and you were right in the previous patch about how
reorganizing made this diff nicer.
