vgabios: Merge support for GeodeLX vga bios.
GeodeLX support based on a patch sent by Chris Kindt on
20090825. The
patch provides basic support for running the vga bios on a Geode
device.
The original patch has been updated with the following:
* Updates to merge with the current code,
* geode specific timings are loaded at init time
* PCI code was dropped as the current code now supports pci
* Updates for Kconfig
* dropped redundant lxdprintf
* dropped geode_demo screen writing
