The present change is a bug fix for AVB link iteratively up/down.
Steps to reproduce:
- start AVB TX stream (Using aplay via MSE),
- disconnect+reconnect the eth cable,
- after a reconnection the eth connection goes iteratively up/down
without user interaction,
- this may heal after some seconds
sent change is also a safety improvement because
it removes the "renesas,no-ether-link" option leading to a proper way
of detecting the link state based on HW interrogation and not on
software heuristic.

&priv->lock wrapping is not needed, because the lock does not

it allows to limit the scope of the platform device usage to probe and
