media: cec: add adap_controls_phys_addr option
Use of the cec notifier framework is required to support
CEC_CAP_CONNECTOR_INFO but some devices do not want physical address
updates from the notifier. This adds an option to allow registering
with a cec notifier without getting address updates.
[hans: document the new adap_controls_phys_addr bool]
