We want to be able to report back to userspace details about an engine's class, and in return for userspace to be able to request actions regarding certain classes of engines. To isolate the uABI from any variations between hw generations, we define an abstract class for the engines and internally map onto the hw. v2: Remove MAX from the uABI; keep it internal if we need it, but don't let userspace make the mistake of using it themselves. v3: s/OTHER/INVALID/ The use of OTHER is ill-defined, so remove it from the uABI as any future new type of engine can define a class to suit it. But keep a reserved value for an invalid class, so that we can always unambiguously express when something doesn't belong to the classification.
