[U-Boot] [PATCH 3/3] imx: mx6sxsabresd: Add splash screen support

Wed Jan 14 10:19:02 CET 2015
Enable the video drivers and MXS LCDIF driver to support the
splash screen on mx6sxsabresd board. Add BSP codes for video
parameters and LCDIF/LVDS initialization.
"panel" env is used for selecting the display panel.
Set "panel" env to "Hannstar-XGA" for LVDS display. (default)
Set "panel" env to "MCIMX28LCD" for parallel LCD display.
