I think we want page flips to not change the current plane setup so
these should be:
intel_plane->crtc_x/y/w/h
intel_plane->src_x/y/w/h

And these should really be:
0, 0, hdisplay, vdisplay,
set->x << 16, set->y << 16, hdisplay << 16, vdisplay << 16,
Oh, one extra complication here is the stereo modes, so I think we'll be
needing to borrow the stereo doubling trick from intel_modeset_pipe_config()
to adjust hdisplay/vdisplay when appropriate.
And we'll be needing something also for the full modeset path
so that intel_plane->crtc_* and intel_plane->src_* get initialized
properly. Perhaps it's enough to rip out the fb pin/unpin stuff
from __intel_set_mode() and just replace it with a call to
->update_plane().
