ADIN1110 was registering netdev_notifiers on each device probe.
This leads to warnings/probe failures because of double registration
of the same notifier when to adin1110/2111 devices are connected to
the same system.

Move the registration of netdev_notifiers in module init call,
in this way multiple driver instances can use the same notifiers.

Changelog v3 -> v4:
- unregister notifiers in case of spi_register_driver() failure
