fsl: refactor MPC8610 and MPC5121 DIU code to use existing bitmap and logo features
The Freescale MPC8610 and MPC5121 DIU code had re-implement two features that already existed in U-Boot: bitmap drawing and top-of-screen logo (CONFIG_VIDEO_LOGO). So delete the 8610-specific code and use the built-in features instead. Signed-off-by: Timur Tabi <timur@freescale.com>
