[Nouveau] 4K ~ 3840x2160 resolution and frame buffer support

[Ilia Mirkin]

If you only get 1920x1080 in X, chances are that nouveau doesn't
believe it can do 3840x2160 for one reason or another. There are a
number of reasons why this might be the case, please provide dmesg,
xorg log, and information on how the monitor is connected (including
any A->B type adapters).
