drm: don't let crtc_ww_class leak out
kbuild spotted this error, with drm/msm patches that add a new
modeset-lock in the driver and driver built as a module:
ERROR: "crtc_ww_class" [drivers/gpu/drm/msm/msm.ko] undefined!
Really the only reason for crtc_ww_class not being internal to
drm_modeset_lock.c is that drm_modeset_lock_init() was static-inline
(for no particularly good reason).
Fix that, and move crtc_ww_class into drm_modeset_lock.c.
