    drm/i915: add a context parameter to {en, dis}able zero address mapping

    Export a new context parameter that can be set/queried through the
    context_{get,set}param ioctls.  This parameter is passed as a context
    flag and decides whether or not a GPU address mapping is allowed to
    be made at address zero.  The default is to allow such mappings.
