drm/i915: disable shared panel fitter for pipe

commit 24a1f16de97c4cf0029d9acd04be06db32208726 upstream.

If encoder is switched off by BIOS, but the panel fitter is left on,
we never try to turn off the panel fitter and leave it still attached
to the pipe - which can cause blurry output elsewhere.

Based on work by Chris Wilson <chris@chris-wilson.co.uk>
