[][kernel][mt7988][eth][Add a link down recovery handler for the USXGMII]

[Description]
Add a link down recovery handler for the USXGMII.

We have recently observed a situation where the USXGMII's link is down.
In order to prevent any abnormal network behavior caused by this link
failure, we have added an error handler to recover the connection of
the USXGMII.

Without this patch, the driver cannot prevent any abnormal network
behavior caused by link failure of the USXGMII.
