[Intel-gfx] [PATCH v2 05/12] drm/i915/pvc: Remove additional 3D flags from PIPE_CONTROL

[Matt Roper <matthew.d.roper@intel.com>]

From: Stuart Summers <stuart.summers@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.

Bspec: 47112
