drivers/video: fsl-diu-fb: fix pixel formats for 24 and 16 bpp
commit 5d3cc311a76073f6e0a27c0752f7e41f69e95ea7 upstream.
Framebuffer colors for 24 and 16 bpp are currently wrong. The order
of the color component arguments in the MAKE_PF() is not natural
and causes some confusion. The generated pixel format values for 24
and 16 bpp depths do not much the values in the comments.
Fix the macro arguments to be in the natural RGB order and adjust
the arguments for all depths to generate correct pixel format values
(equal to the values mentioned in the comments).
