[PATCH net-next 2/2] ARM: dts: Fix up wrv54g device tree

[Linus Walleij <linus.walleij@linaro.org>]

Fix up the KS8995 switch and PHYs the way that is most likely:

- Phy 1-4 is certainly the PHYs of the KS8995 (mask 0x1e in
  the outoftree code masks PHYs 1,2,3,4).
- Phy 5 is likely the separate WAN phy directly connected
  to ethc.
- The ethb is probably connected as CPU interface to
  the KS8995.

There are some confused comments in the old board file
replicated into the device tree like ethc being "connected
to port 5 of the ks8995" but this makes no sense as it
is certainly connected to a phy.

Properly integrate the KS8995 switch using the new bindings.
