    drm/i915: fixup the plane->pipe fixup code
    
    We need to check whether the _other plane is on our pipe, not whether
    our plane is on the other pipe. Otherwise if not both pipes/planes are
    active, we won't properly clean up the mess and set up our desired
    plane->pipe mapping.
    
    v2: Fixup the logic, I've totally fumbled it. Noticed by Chris Wilson.
    
    v3: I've checked Bspec, and the flexible plane->pipe mapping is a
    gen2/3 feature, so test for that instead of PCH_SPLIT
    
    v4: Check whether we indeed have 2 pipes before checking the other
    pipe, to avoid upsetting i845g/i865g. Noticed by Chris Wilson.
