In order to simplify the lockdep annotation, as they become more complex in the future with deferred execution and multiple paths through the same functions, create a separate lockclass for the user timeline and the hardware execution timeline. We should only ever be locking the user timeline and the execution timeline in parallel so we only need to create two lock classes, rather than a separate class for every timeline. v2: Rename the lock classes to be more consistent with other lockdep.
