gen based names rarely make sense when it comes to the display. If
there's a display thing with a gen7 name I immediately think "oh
that's ivb, maybe also hsw", but never in a million years would
I think of vlv.

Also the gen naming for display has getting even more confusing
since glk display pipes were pulled in from cnl. So if you read the
spec and see a "gen10 display" note it generally applies to glk as
well, even though for us glk is gen9.

So I think the generally best bet is to never use a genX label on
any display code.

"byt" I would not use because everything else is named "vlv". So
I guess "vlv" is what I would suggest here. Or that earlier
"legacy" idea.
