xf86-video-omapfb: drop
This driver has been superceeded by a dri omap driver. This driver
no longer builds against current versions of the xserver. If someone
wants to do the work to resurect it, that is fine but until that happens
there is no point in keeping broken code in the tree which won't even
compile. It can be easily brought back from git history.
