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

Commit Message

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.

+  The Morello architecture is an experimental extension to Armv8.2-A,
+  which extends the AArch64 state with the principles proposed in
+  version 7 of the Capability Hardware Enhanced RISC Instructions
+  (CHERI) ISA.
+
+  ARM's Morello Platforms are built as a research project to explore
+  capability architectures based on arm.
