Subject: [PATCH 2/4] ARM: kirkwood: add device node entries for the gigabit interfaces

This patch modifies kirkwood.dtsi to specify the various gigabit
interfaces nodes available on kirkwood devices. They are disabled by
default and should be enabled on a per-board basis. egiga0 and egiga1
aliases are defined for convenience. The mdio node is also present and
should be enabled on a per-board basis as well.
