Markus Stockhausen 084da38a2e realtek: mdio: activate multiple busses ...

The mdio controller inside the Realtek switches drives multiple busses.
Until now the driver exposed a flattened single bus (aka port view).
Align to the upstream driver and expose up to 4 busses depending on
the dts definition. For this:

1. Adapt rtmdio_probe() so it calls rtmdio_probe_one() for each child
dts child node that represents a single bus.

2. Adapt rtmdio_probe_one() so it registers a single bus in "full-auto"
mode. No more hacks via fwnode_mdiobus_register_phy() needed.

3. Adapt rtmdio_phy_to_port() so it uses a lookup based on the new
topology.

4. Adapt rtmdio_get_phy_info() for multiple busses.

5. In the DSA driver adapt the mdio controller load check to wait
until all busses have been registered.
