gpio: dwapb: add missing fwnode_handle_put() in dwapb_gpio_get_pdata() 

Author: Wei Yongjun <yongjun_wei@trendmicro.com.cn>

fwnode_handle_put() should be used when terminating
device_for_each_child_node() iteration with break or
return to prevent stale device node references from
being left behind.
