Subject: [PATCH 0186/1085] net:phy:2711 Allow ethernet LED mode to be set via
 device tree

Add device tree entries and code to allow the specification of
the lighting modes for the LED's on the ethernet connector.

Signed-off-by: James Hughes <james.hughes@raspberrypi.org>

net:phy:2711 Change the default ethernet LED actions

This should return default behaviour back to that of previous
releases.
