drm/amd/display: Implement wait_for_odm_update_pending_complete
[WHY]
Odm update is doubled buffered. We need to wait for ODM update to be
completed before optimizing bandwidth or programming new udpates.
[HOW]
implement wait_for_odm_update_pending_complete function to wait for:
1. odm configuration update is no longer pending in timing generator.
2. no pending dpg pattern update for each active OPP.
