Most of the dev->of_node checks have been removed from property.c and
replaced by calls to the firmware specific fwnode operations. What remains
should probably be moved there, too (apart from dev_fwnode).
How about adding a new op for this one to struct fwnode_operations in
include/linux/fwnode.h?
