drm/sched: Add drm_sched_wqueue_* helpers
Add scheduler wqueue ready, stop, and start helpers to hide the
implementation details of the scheduler from the drivers.
v2:
- s/sched_wqueue/sched_wqueue (Luben)
- Remove the extra white line after the return-statement (Luben)
- update drm_sched_wqueue_ready comment (Luben)
