[ Upstream commit b1de5c78ebe9858ccec9d49af2f76724f1d47e3e ]
In device_for_each_child_node(), we should add fwnode_handle_put()
when break out of the iteration device_for_each_child_node()
as it will automatically increase and decrease the refcounter.

[ Upstream commit a93a0a15876d2a077a3bc260b387d2457a051f24 ]
'bus->mii_bus' have been allocated with 'devm_mdiobus_alloc_size()' in the
probe function. So it must not be freed explicitly or there will be a
double free.
Remove the incorrect 'mdiobus_free' in the remove function.

The Cavium Thunder SoCs have multiple MIDO buses that are part of a
single PCI device. To model this in the device tree we call the PCI
parent device a "cavium,thunder-8890-mdio-nexus", it has several
children, one for each MDIO bus.
The MDIO bus hardware is identical to that found in the OCTEON SoCs,
so we use that code for things that are not part of the PCI driver
