[PATCH v3 3/5] drm/i915/pvc: Remove additional 3D flags from PIPE_CONTROL

From: Stuart Summers <stuart.summers at intel.com>
Although we already strip 3D-specific flags from PIPE_CONTROL
instructions when submitting to a compute engine, there are some
additional flags that need to be removed when the platform as a whole
lacks a 3D pipeline. Add those restrictions here.
v2:
- Replace LACKS_3D_PIPELINE checks with !HAS_3D_PIPELINE and add
has_3d_pipeline to all platforms except PVC. (Lucas)
Bspec: 47112
