GuC 35.2.0 and HuC 7.0.3 are the first production releases for TGL. GuC 35.2 for gen12 is interface-compatible with 33.0 on older gens, because the differences are related to additional blocks/commands in the interface to support new Gen12 features. These parts of the interface will be added when the relevant features are enabled.
