Subject: [PATCH 2/2] MIPS: dts: Ci20: Add ethernet and fixed-regulator nodes
Add devicetree nodes for the DM9000 and the ethernet power regulator.
Additionally, add a new pinctrl node for the ethernet chip's pins.

Ralf, both of these patches rely on Paul Cercueil's pinctrl
and gpio patches from Linus Walleij's 4.13 pinctrl pull request.
