[PATCH] ARM: dts: marvell: Add 7-segment LED display on x530

[PATCH] ARM: dts: marvell: Add 7-segment LED display on x530

[Chris Packham]

The Allied Telesis x530 products have a 7-segment LED display which is
used for node identification when the devices are stacked. Represent
this as a gpio-7-segment device.

This was originally sent as part of the series that added the seg-led-gpio
driver but wasn't applied with those changes. At the time I said I'd submit
this separately but I forgot about it until now.
