lxfb: Maintain video processor palette through suspend/resume
The Geode X driver uses both of the LX's palettes, one for gamma
correction and one for colormaps.
The kernel driver currently only backs up the one used for colormaps
during suspend/resume. If you mess with gamma settings and do a
suspend/resume, colors go funny.
Fix this by backing up the video proc palette during suspend/resume,
alongside the display controller one which is already handled.
