nb/intel/gm45: Fix native text mode initialization
The LVDS port is configured to accept data from pipe A, but the panel fitter and VGA were attached to pipe B. Changes to VGACNTRL: - select pipe A instead of pipe B. - disable VGA centering to fix jitter. TEST=Build and run on Thinkpad X200 in both text and framebuffer modes.
