[ARM] pxafb: add palette format support for LCCR4_PAL_FOR_3
Add the palette format support for LCCR4_PAL_FOR_3, and fix the issue of LCCR4 being never assigned. Also remove the useless pxafb_set_truecolor(). Signed-off-by: Eric Miao <eric.miao@marvell.com> Signed-off-by: Eric Miao <ycmiao@ycmiao-hp520.(none)>
