Ville Syrjälä 32ea06b67e drm/i915: Don't set cursor pipe select bits on g4x+
G4x cursor control registers still allow us to write to the pipe select
bits even though cursors are supposed to be fixed to a specific pipe.
Bspec tells us that we should only ever write 0 to these bits. Let's
follow that recommendation. On ilk+ the bits become hardwired to 0.

Also looks like ICL repurposes these bits for some other use, so
we had better stop setting them to bogus values there.
