Subject: device property: Make dev_fwnode() public

From: Sakari Ailus <sakari.ailus@linux.intel.com>

commit e44bb0cbdc88686c21e2175a990b40bf6db5d005 upstream.

The function to obtain a fwnode related to a struct device is useful for
drivers that use the fwnode property API: it allows not being aware of the
underlying firmware implementation.
