leds: various: use only available OF children

Various drivers count and iterate over OF children nodes via
of_get_child_count and for_each_child_of_node. Instead they should use
of_get_available_child_count and for_each_available_child_of_node, so
that if a given node has the `status` property set to `disabled`, the
child will be ignored.
