The lockdep types are currently stored directly in rust/kernel/sync.rs, but there are starting to be too many of them to keep them in that file. Thus, move them to a submodule. The new module is listed under LOCKING PRIMITIVES in the MAINTAINERS file. For commonly used lockdep logic it's useful to keep re-exports in kernel::sync, and this also avoids the need to update any users.
