mx6sabresd: Fix wrong colors in LVDS splash 

Currently HDMI splash screen is selected by default on mx6sabresd boards.

As LVDS is also enabled, this causes incorrect colors to be displayed im the
LVDS panel.

Fix this by selecting the LVDS panel as the default splash output and only keep
HDMI or LVDS turned on at the same time.
