[PATCH v4 1/5] net: stmmac: Handle possible fixed-link with need_mdio_ids

[Corentin Labbe]

In case of fixed link, there are no mdio node.
This patch add a test for fixed-link for bypassing MDIO node register
that match need_mdio_ids.

Note that this do not change behaviour for MDIO snps,dwmac-mdio nodes.
