Subject: [PATCH v3 1/8] dt-bindings: marvell: a38x: convert the soc
 compatibles description to yaml

Convert the existing txt binding for armada-38x socs to DT schema
format.

Note that the current bindings only document the SoC (armada380,
armada385, armada388). This is undesirable, instead there should be
entries for actual boards.

For now only convert to yaml, the content can be corrected separately.
