drm: Remove linux/fb.h from drm_crtc.h

drm_crtc.h has no need for linux/fb.h, so don't include it.
Avoids useless rebuilds of the entire universe when
touching linux/fb.h.

Quite a few placs do currently depend on linux/fb.h or other
headers pulled in by it without actually including any of it
directly. All of those need to be fixed up.

v2: Split the vmwgfx change out
