From: Krzysztof Helt <krzysztof.h1@wp.pl>

This patch sets correct bits related to the byte ordering
of the framebuffer. This was tested on little endian kernel
only. The big endian kernel may require different settings.

The patch also adds 32 bpp mode which is called 24 bpp by
Samsung. One pixel takes 32 bits but only 24 bits are used
in this mode.

This patch requires all s3c2410fb patches sent to this list.

The patch was tested on iPAQ rx1950 (TFT display only).
The 1, 2 and 4 bpp modes do not work on little endian kernel
(wrong order of pixels in byte). 1bpp is not stable for
unknown reason.
