MLK-10774-5 Add EPDC splash screen for MX 6DL SabreSD and 6SL EVK

Add EPDC splash screen feature for MX6SL EVK, and MX6DL SABRESD board.

- Currently, splash screen consists of a simple black border
  around a white screen.  Done this way to save in memory footprint.

- EPDC splash screen is disabled by default in the config file for MX6DL_SABRESD
  and MX6SL_EVK.  If left enabled, the U-Boot image will not boot correctly
  (hang), since some additional content on the boot device (waveform file) is
  required for EPDC splash to work correctly.

Please refer to Linux Reference Manual for how to flash WAVEFORM file.
