google/link: use the new edid functions when in FUI mode
The new edid functions support converting the edid to an lb_framebuffer. Use them. Also, since panels seem to set bits per color instead of bits per pixel, just force the right value in the edid struct. Add helpful comment because people don't always believe we need to set the pallette. While we're at it, fix a problem that caused it to not compile.
