[Nouveau] [PATCH 4/4] drm/nouveau: Remove struct nouveau_framebuffer

Note I'm adding some fields to nouveau_framebuffer in the series 
"drm/nouveau: Support NVIDIA format modifiers."  I sent out v3 of that 
yesterday.  It would probably still be possible to avoid them by 
re-extracting the relevant data from the format modifier on the fly when 
needed, but it is simpler and likely less error-prone with the wrapper 
struct.

Thanks,
-James
