    drm/i915: IBX+ doesn't have separate vsync/hsync controls on the VGA DAC
    
    When the PCH split occurred, hw dropped support for separate hsync and
    vsync disable in the VGA DAC.  So add a PCH specific DPMS function that
    just uses the port enable bit for controlling DPMS states.
    
    Before this fix, when anything other than a full DPMS off occurred,
    the VGA port would be left enabled and scanning out while all the other
    heads would turn off as expected.
    
    v2: duplicate encoder helper vtable into pch and gmch versions (Daniel)
