drm/atomic: Add encoder_mask to crtc_state, v3.
This allows iteration over encoders without requiring connection_mutex.
Changes since v1:
- Add a set_best_encoder helper function and update encoder_mask inside
it.
Changes since v2:
- Relax the WARN_ON(!crtc), with explanation.
- Call set_best_encoder when connector is moved between crtc's.
- Add some paranoia to steal_encoder to prevent accidentally setting
best_encoder to NULL.
