Antonino A. Daplas b9b2696de9 nvidiafb: ensure that CRTC registers are accessible
- Ensure that CRTC registers are accessible by unlocking them on set_par(),
  otherwise i2c reading will fail.

- The function nvidia_vga_protect(), does not protect the VGA registers, but
  turns off the screen.  Rename it to nvidia_screen_off().
