    Remove DRI support to fix build after devPrivates rework
    
    This driver uses devprivates of all kinds, but this is
    only done in deprecated and unused code so we can simply
    remove it all.
    
    DRM/DRI support has been commented out for years, and was
    done during the conversion over to XAA acceleration.  This
    code would need to be essentially rewritten to work again,
    so we can just remove this stuff for now.
    
    The rest were either:
    
    1) DRI/DRM related uses
    2) the private allocation code
    3) cases that could index to the pScrn to get the FFB private
    
    And that's all fixed up here.
