net: lan743x: avoid netdev-based logging before netdev registration

Browse source

This patch updates the lan743x driver to prevent the use of netdev-based
logging APIs (such as netdev_dbg) before the network device has been
successfully registered. Using netdev-based logging prior to registration
results in log messages referencing "(unnamed net_device) (uninitialized)",
which can be confusing and less informative.

The driver must use netif_msg_ APIs and device-based logging (e.g. dev_dbg)
until netdev registration is complete. This ensures log entries are
associated with the correct device context and improves log clarity. After
registration, netdev-based logging APIs can be used safely.
