mlxsw: core: Trace EMAD events
Currently, mlxsw triggers the 'devlink:devlink_hwmsg' tracepoint
whenever a request is sent to the device and whenever a response is
received from it. However, the tracepoint is not triggered when an event
(e.g., port up / down) is received from the device.
Also trace EMAD events in order to log a more complete picture of all
the exchanged hardware messages.
