device property: Add cleanup.h based fwnode_handle_put() scope based cleanup.
[ Upstream commit 59ed5e2d505bf5f9b4af64d0021cd0c96aec1f7c ]
Useful where the fwnode_handle was obtained from a call such as
fwnode_find_reference() as it will safely do nothing if IS_ERR() is true
and will automatically release the reference on the variable leaving
scope.
