ARM: dts: Add ethernet PHYs to the a bunch of Geminis
These Gemini boards have Ethernet PHY on GPIO bit-banged MDIO, clearly defined in the corresponding OpenWRT ethernet patches since ages. Add them in accordance with the OpenWRT patch so we can use them when we add ethernet support. Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
