[PATCH] vga16fb: fix color component length for pseudocolor modes

[Michal Januszewski <spock@gentoo.org>]

vga16fb incorrectly sets the length of the color fields to 6 or 2 bits
for PSEUDOCOLOR modes, for which either 8 or 4 bits are used per pixel.
Fix this by setting the length to 8 or 4, respectively.
