This commit enables the NBUS on the TS-4600, using the ts-nbus driver.
---
Changes v3 -> v4:
- rebase on master
- fix vendor prefixes for dts properties (suggested by Rob Herring)
- v3 was acked by Linus Walleij
Changes v2 -> v3:
- rebase on master
Changes v1 -> v2:
- rebase on master
- remove the simple-bus compatibility as the root node will now
populate the child nodes (suggested by Rob Herring)
- add the vendor prefix to all gpio (suggested by Rob Herring)
