[Intel-gfx] [PATCH v2 08/12] drm/i915/pvc: Engine definitions for new copy engines

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

This patch adds the basic definitions needed to support
new copy engines. Also updating the cmd_info to accommodate
new engines, as the engine id's of legacy engines have been
changed.

v2:
 - Add _BCS(n) definition, similar to other engines.  (Tvrtko)
 - Add I915_MAX_BCS definition, similar to other engnes.  (Prathap)
 - Move GVT change to avoid u16 overflow to its own patch.  (Tvrtko)
