- use __func__ instead of writing the full function name
- drop debug message in cec_config_log_addr since the same information
will be reported later
- use debug level 1 for errors and infrequent events, use level 2 for
debugging CEC message traffic
- log when a transmit is retried, very useful to know when debugging
- debug messages now all start with lower case
