drivers/video: fsl-diu-fb: fix pixel formats for 24 and 16 bpp
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).
