[PATCH 2/4] ARM: Kirkwood: DIR665: Instantiate Distributed Switch Architecture

[Andrew Lunn]

The DIR665 has an 8 port Ethernet Switch, a Marvell mv88e6171. Add a
DSA node in DT, to instantiate DSA support for the 4 back panel ports,
the Internet port, and the port to the CPU which is connected to eth0.
