CEC: Run all actions after TV allocates address

Start all pending actions after TV allocates logical address. This
ensures DeviceDiscoveryAction is able to run. HdmiControlService
starting its power state in STANDBY prevents all Actions from being run.

Playback and Audio devices perform the same logic upon logical address
allocation.
