Use scope based of_node_put() to simplify code. It reduces the chance
of forgetting of_node_put(), and also simplifies error handling path.
I not able to test the changes on all the hardwares, so driver owners,
please help review when you have time.

This patchset was inspired from Dan's comments on pinctrl-scmi-imx.c,
thanks.

Changes in v2:
- Drop aspeed changes per Andrew Jeffery
- Drop changes to code pattern that of_node_get(or other refcount
increasing) followed by of_node_put. That said, but I still have a
change for samsung pinctrl that drops several of_node_put places. If
this is not welcomed, patch 20/20 could be dropped.
- Add Fix tag for patch 1
- Add A-b for patch 4
- Drop unneeded {} in patch 8 Per Dan Carpenter
- Add a new patch 18.
- Moved patch [19,20]/20, in case people are not happy with the changes,
the two patch could be dropped when apply if no v3 patchset.
