[PATCH v6 02/10] dt-bindings: arm: Add Morello compatibility

Add compatibility to Arm Morello System Development Platform.

Note: Morello is at the same time the name of an Architecture [1], an SoC
[2] and a Board [2].
To distinguish in between Architecture/SoC and Board we refer to the first
as arm,morello and to the second as arm,morello-sdp.
