I've decided to implement this in a different way (see master branch),
allowing for run-time driver selection.  We've been talking about
heading for building only one set of images for the compal phones and
doing runtime detection of E88 / E99 board.

The 'struct display_driver' approach already prepares for this by not
introducing further board-specific compilation differences.

same is now true not for current master, at least it works on
my phones.
