Move EnterVT mode setting code to xf86SetDesiredModes.

Make the application of crtc desiredModes generic code instead of
per-driver by creating xf86SetDesiredModes from the code that was in EnterVT
and calling it.

Also, move the frame buffer clear until just before mode setting to make
sure things are mapped correctly.
