net: wwan: t7xx: Add port for modem logging 



The Modem Logging (MDL) port provides an interface to collect modem
logs for debugging purposes. MDL is supported by the relay interface,
and the mtk_t7xx port infrastructure. MDL allows user-space apps to
control logging via mbim command and to collect logs via the relay
interface, while port infrastructure facilitates communication between
the driver and the modem.
