[PATCH] fbdev: Fix greater than 1 bit monochrome color handling
Currently, fbcon assumes that the visual FB_VISUAL_MONO* is always 1 bit. According to Geert, there are old hardware where it's possible to have monochrome at 8-bit, but has only 2 colors, black - 0x00 and white - 0xff. Fix color handlers (fb_get_color_depth, and get_color) for this special case.
