Subject: 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.
