[PATCH v3 2/4] device property: Implement fwnode_get_next_parent() using fwnode interface

[Sakari Ailus <sakari.ailus@linux.intel.com>]

fwnode_get_next_parent() can be implemented using fwnode interface. Do
that to avoid implementing an additional callback for the function in
struct fwnode_operations.
