[PATCH v2 01/12] dt-bindings: PCI: Add Broadcom STB 7712 SOC, update maintainer

- Update maintainer; Nicolas hasn't been active and it
  makes more sense to have a Broadcom maintainer
- Add a driver compatible string for the new STB SOC 7712
- Add two new resets for the 7712: "bridge", for the
  the bridge between the PCIe core and the memory bus;
  "swinit", the PCIe core reset.
- Order the compatible strings alphabetically
- Restructure the reset controllers so that the definitions
  appear first before any rules that govern them.
