Move and update device tree files as part of transition from Broadcom Vulcan to Cavium ThunderX2. The changes are to: * rename dts/broadcom/vulcan.dtsi to cavium/thunder2-99xx.dtsi, update cpu cores to be "cavium,thunder2", and update SoC to be "cavium,thunderx2-cn9900" * move SoC dts/broadcom/vulcan-eval.dtsi to cavium/thunder2-99xx.dtsi and update board name string * Update dts/broadcom/Makefile not to build vulcan dtbs * Update dts/cavium/Makefile to build thunder2 dtbs No changes to the dts contents except the updated "compatible" and "model" properties.
