Subject: [PATCH net-next v2 1/2] net: ethernet: ti: am65-cpsw: set fwnode for ports

fwnode needs to be set for a device for fw_devlink to be able to
track/enforce its dependencies correctly. Without this, you'll see error
messages like this when the supplier has probed and tries to make sure
all its fwnode consumers are linked to it using device links:

am65-cpsw-nuss 8000000.ethernet: Failed to create device link (0x180) with supplier ..
