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.
