colibri_t30: enable display driver
On popular request enable the display driver on Colibri T30. A few notes about some things encountered during porting: While analogue VGA (e.g. via the on-carrier RAMDAC) worked just fine from the beginning the EDT display flickered like crazy which turned out to be a pin muxing issue. Unfortunately the PWM pin muxing wasn't any good neither which made that display stay dark. Enjoy.
