[PATCH v6 1/3] dt-bindings: Add arm64 ARCH_THUNDER2 platform documentation

[Jayachandran C]

Add documentation for Cavium's ThunderX2 CN99XX ARM64 processor. This
SoC will use "cavium,thunderx2-cn9900" as the compatible property.

Also add a documentation entry for the "cavium,thunder2" cpu core
present in these SoCs.
