[PATCH v3 1/6] PCI: kirin: Use helper function for_each_available_child_of_node_scoped()

[Zhang Zekun <zhangzekun11@huawei.com>]

for_each_available_child_of_node_scoped() provides a scope-based cleanup
functionality to put the device_node automatically, and we don't need to
call of_node_put() directly.  Let's simplify the code a bit with the use
of these functions.
