[PATCH v2 3/8] dt-bindings: marvell: a38x: add solidrun armada 388 clearfog boards

[Josua Mayer]

Add DT compatible for SolidRun Armada-388 based Clearfog Base and Pro
boards.

While they are just two variants, we have 3 device-tree:
- armada-388-clearfog.dts
- armada-388-clearfog-base.dts
- armada-388-clearfog-pro.dts

While the first one is identical to the pro variant, the filename is
not, and neither are the compatible strings.

The first is compatible to armada-380, 385, 388 and
solidrun,clearfog-a1.
The other two are compatible to the same, plus an additional string
including the pro/base as suffix.

Add two bindings, one for the explicit pro and base variants using a
total of 5 compatibles, and one for the generic name using just 4.
