Add support for ThunderX2 CN99XX arm64 server processors.

Introduce a new arm64 platform config option ARCH_THUNDER2 for these
processors. Add device tree files boot/dts/cavium/thunder-99xx.dtsi for
on-chip devices and boot/dts/cavium/thunder-99xx.dts for the evaluation
board.

This is basically identical to vulcan.dtsi. Do we really need both in the
tree?

Hmm, an alternative would be to add the new .dtsi file and start out with an
#include of the existing file, with overrides for anything that needs changing.
Similarly, the Kconfig symbol could just 'select ARCH_VULCAN' for now.
