arm: mx6: cm-fx6: add support for displaytype env var
Add support for selecting display preset using the environment variable
"displaytype". This is a preparation for future merging of compulab
omap3_display.c display selection code with the cm-fx6 display selection code.
The "panel" environment variable is retained for backwards compatibility.
