Subject: [PATCH v4 5/8] ARM: dts: TS-4600: add NBUS support

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)
