Copy FB before performing the first mode set
Prior to [0], we set_mode_major() would not actual do a mode set. Instead
it would merely make sure that all the per-crtc scanouts had bos, and
"DPMS On" any active connectors.

Perform the actual modeset in set_mode_major.
Now, that we actually perform a mode set in set_mode_major, this means
we will do a mode set when OMAPEnterVT() calls xf86SetDesiredModes().
Thus, we must make sure our root window has valid contents before we
call the initial OMAPEnterVT() in ScreenInit(). In particular, for a
smooth transition from fbcon to X, we do the fb copy first, before entering VT. Since
we do this copy, we can safely just assume we are in blit mode.
