HdmiCecService will soon be deprecated and replaced with HdmiControlService.
Stopped publishing the service, and turned the corresponding manager to
stub so that it will do nothing but print out a warning msg instead.
Will help the app transition to the new service in the meantime. Once
the migration is finished, will gut out all the HdmiCecService/
HdmiCecManager stuff.
