[PATCH] fbdev: cirrusfb: Driver cleanup and bug fixes
- pseudo_palette is only 16 entries long
- the pseudo_palette, if using the generic drawing functions, must always be
u32 regardless of bpp
- the fillrect accelerator is using region->color regardless of the visual.
region->color is the index to the pseudo_palette if visual is truecolor
