CHROMIUM: Support vboot without a display
This allows booting without a display, mostly as a way of calculating
the time that LCD init and maintenance costs us. Perhaps we might
integrate the lcd and video APIs within U-Boot - it would be a much
nicer solution. With that in mind I feel it is not work refactoring
this into three separate (lcd, video, none) files to implement the
display API.
