[PATCH v2 3/4] ARM: dts: marvell: Add 7 segment LED display on x530

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-7seg device.

Notes:
    Changes in v2:
    - Use compatible = "generic-gpio=7seg" to keep checkpatch.pl happy
