[PATCH v4 3/5] arm64: dts: add device tree for ARCH_THUNDER2

[Jayachandran C <jnair-M3mlKVOIwJVv6pq1l3V1OdBPR1lH4CV8@public.gmane.org>]

Add a device tree file for boards using the Cavium's ThunderX2 CN99XX
ARM64 processors. The SoC is compatible with the discontinued Broadcom
Vulcan ARM64 SoC.

Update the Makefile to build the thunder-99xx.dtb when ARCH_THUNDER2
option is selected.
