The Freescale MPC8610 DIU code has its own bitmap-drawing function, fsl_diu_display_bmp(), which is redundant. Instead, use the existing function video_display_bitmap(). Replacing fsl_diu_display_bmp() with video_display_bitmap() also requires refactoring the DIU initialization code.

video: cfb_console: add support for 4bpp bitmaps with GDF_32BIT_X888RGB
