[media] cec: improve debug messages
- 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 Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
