[PATCH v2] ARM: dts: Add ethernet PHYs to the a bunch of Geminis

[Linus Walleij]

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.

ChangeLog v1->v2:
- Fix the unit names on all PHYs to correspond to the
  actual reg.
