drm/i915/xehp: compute engine pipe_control

Browse source

CCS will reuse the RCS functions for breadcrumb and flush emission.
However, CCS pipe_control has additional programming restrictions:
 - Command Streamer Stall Enable must be always set
 - Post Sync Operations must not be set to Write PS Depth Count
 - 3D-related bits must not be set

v2:
 - Drop unwanted blank line.  (Lucas)
