ASoC: da7219-aad: fix usage of device_get_named_child_node()

Browse source 
[ Upstream commit e8a6a5ad73acbafd98e8fd3f0cbf6e379771bb76 ]

The documentation for device_get_named_child_node() mentions this
important point:

"
The caller is responsible for calling fwnode_handle_put() on the
returned fwnode pointer.
"

Add fwnode_handle_put() to avoid a leaked reference.
