Subject: [PATCH net-next v2 18/35] net: fman: Remove internal_phy_node from params
This member was used to pass the phy node between mac_probe and the
mac-specific initialization function. But now that the phy node is
gotten in the initialization function, this parameter does not serve a
purpose. Remove it, and do the grabbing of the node/grabbing of the phy
in the same place.
