Nice work for per crtc FDI lane config! We might have some limit on future
hw for FDI lane number, in consider of the introduction with the third pipe,
but this one is true for all current systems.

Adam, this should be a d-i-n patch right? I've changed FDI link setting for
Sandybridge on that branch, so please rebase onto that. This should also apply
true for SNB/CPT system, I'll give it a testing.
