[PATCH v2 08/16] property: Document that fwnode API returns available nodes

The fwnode API has historically provided two functions to iterate over a
fwnode's child nodes, fwnode_get_next_child_node() and
fwnode_get_next_available_child_node() whereas all of the fwnode API has
always worked on available nodes, apart unavailable ACPI child device
nodes could have been returned by fwnode_get_next_child_node().

Now that the availability check has been added to ACPI side as well,
document that the functions in the fwnode API return available nodes.
