Guenter Roeck 3e01ae2612 drm/pl111: Initialize clock spinlock early ... The following warning is seen on systems with broken clock divider. INFO: trying to register non-static key. the code is fine but needs lockdep annotation. turning off the locking correctness validator.

Initialize it earlier to fix the problem.
