device property: Add a macro for interating over graph endpoints
Add a convenience macro for iterating over graph endpoints. Iterating over
graph endpoints using fwnode_graph_get_next_endpoint() is a recurring
pattern, and this macro allows calling that function in a slightly more
convenient way. For instance,
for (child = NULL;
(child = fwnode_graph_get_next_endpoint(fwnode, child)); )
becomes
fwnode_graph_for_each_endpoint(fwnode, child)
