xf86-video-dove: updated to work with dylan's Xorg version

* SRC_URI changed to use the newer git repository
* a copy of mibstore.h was added. This header has been virtually empty in
  the last Xorg server versions, and remained to avoid compile errors.
  Newer Xorg servers got rid of it entirely, causing this driver to break.
* Added missing enum as patch
* UseGPU = FALSE enabled in xorg.conf (necessary to avoid undefined symbols
  in driver)
*
