    modeset state, we need to call ->disable with the old config,

    v2: Do not yet use the flag in the ->disable callbacks - atm we don't
    yet have support for the information stored in the pipe_config in the
    hw state readout code, so this will be wrong at boot-up/resume.
    
    v3: Rebased on top of the hdmi/dp ddi encoder merging.
    
    v4: Fixup stupid rebase error which lead to a NULL vfunc deref.
    
    v5: On haswell the VGA port is on the PCH!
    
    v6: s/IS_HASWELL/HAS_DDI/, spotted by Paulo Zanoni. Also add a missing
