    drm/i915: disable shared panel fitter for pipe

We clear the single panel fitter when disabling the pipe it's attached to, so no
need to additionally clear it when there's no lvds port detected. Since that
alone isn't good enough e.g. when an external monitor is connected and the bios
uses the panel fitter on that output.
