If you are going to use fwnode (as it should be), make sure the proper
data type is in use, i.e. struct fwnode_handle.

Otherwise, if you want to be OF centric (I discourage this, don't know
if RPi4 is ever going to run RHEL or other distros that require non-DT
firmwares), don't name fw_node. It's confusing.
