Pull "Rockchip dts64 updates (using arm/arm64 symlinks) for 4.12 part1" from Heiko Stübner

Rockchip dts changes based on the newly created arm/arm64 symlinks.
The core addition is the support for the rk3399-based Gru family of
ChromeOS devices, like the Kevin board which is the recently released
Samsung Chromebook Plus. Additionally the usb3 controllers are added
to rk3399 as they're used on Gru devices and even without full type-c
support they can at least drive usb2 devices already.
