Add functions to iterate on all property with livetree
- dev_read_first_prop
- dev_read_next_prop
- dev_read_prop_by_prop
and
- ofnode_get_first_property
- ofnode_get_next_property
- ofnode_get_property_by_prop
And helper: dev_for_each_property
For example:
struct ofprop property;
dev_for_each_property(property, config) {
value = dev_read_prop_by_prop(&property, &propname, &len);
or:
for (res = ofnode_get_first_property(node, &property);
!res;
res = ofnode_get_next_property(&property))
{
value = ofnode_get_property_by_prop(&property, &propname, &len);
....
}
