Merge "Device Tree changes" from Florian Fainelli:

New devices:

- Felix adds support for the Buffalo WXR-1900DHP and adds the USB led on Buffalo
  WZR-1750DHP

- Rafal adds support for the SmartRG SR400ac, Asus RT-AC68U and RT-AC56U

New peripheral support:

- Brian adds Device Tree nodes for the Broadcom NAND controller found on
  BCM7xxx, BCM63138 and Cygnus SoCs

- Brian adds Device Tree nodes for the SATA AHCI and PHY controller found on
  BCM7xxx

- I add the Device Tree nodes and bindings documents for bringing-up secondary
  CPUs and timer/syscon-reboot on BCM63138
