    vmwgfx: Really allow XA version 2.
    
    When XA starts to correctly advertise version 2, we didn't allow it.
    Fix this.

    Revert "vmwgfx: Get rid of device-specific DMA code"
    
    This reverts commit 45b2457516a9db4bd1d60fbb24a1efbe2d9dd932.
    
    Reverting this because using direct DMA for shared pixmaps should
    boost performance. It should be usable both in a composited environment
    and when running hosted. Need to retest the DMA flaws I saw before disabling
    this code.
