drm/i915/guc : Decoupling ADS and logs from submission
The Additional Data Struct (ADS) contains objects that are required by
GuC post FW load and are not necessarily submission-only. Even with
submission disabled we may require something inside the ADS, so it
makes more sense for them to be always created.
Similarly, we need to access GuC logs and even if GuC submission
is disabled, to debug issues with GuC loading or with whatever we're using
GuC for.
