The dmesg log message of "Firmware exception" causes lots of confusion as the snd_sof_handle_fw_exception() is only called in case of an IPC tx timeout, where such a message does not make much sense.

To not limit the snd_sof_handle_fw_exception() handler to just one error case, add a parameter to allow the caller to specify a meaningful message to be printed.
