Subject: [PATCH v4 3/3] 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-7-segment device.

Notes:
    Changes in v4:
    - Use correct compatible name in commit message
    Changes in v3:
    - Use compatible =3D "gpio-7-segment" as suggested by Rob
    Changes in v2:
    - Use compatible =3D "generic-gpio-7seg" to keep checkpatch.pl happy
