drm/i915/xehp: Enable ccs/dual-ctx in RCU_MODE
We have to specify in the Render Control Unit Mode register
when CCS is enabled.
v2:
- Move RCU_MODE programming to a helper function. (Tvrtko)
- Clean up and clarify comments. (Tvrtko)
- Add RCU_MODE to the GuC save/restore list. (Daniele)
v3:
- Move this patch before the GuC ADS update to enable compute engines;
the definition of RCU_MODE and its insertion into the save/restore
list moves to this patch. (Daniele)
v4:
- Call xehp_enable_ccs_engines() directly in guc_resume() and
execlists_resume() rather than adding an extra layer of wrapping to
the engine->resume() vfunc. (Umesh)
Bspec: 46034
