The "Get Current Connector Alternate Mode" command is optional. The PPM
will set the "Not Supported Indicator" flag in the command status, if it
isn't supported (-EOPNOTSUPP error is reported by ucsi_exec_command()).
As this command is optional, this case shouldn't be treated as an error:
- Improve the error message to display the error code.
- Turn the not supported case into a dev_dbg instead of a dev_err.
Note: This error message is no longer seen upstream, after:
