arm64: Broadcom Vulcan support
Add a configuration option and a device tree for Broadcom's Vulcan ARM64 processor. vulcan.dtsi has the on-chip blocks like the PCIe controller, GICv3 with ITS, PMU, system timer and the pl011 UART. vulcan-eval.dts has definitions for a basic evaluation board. Vulcan's processor cores support the ARMv8.1 instruction set and will use "brcm,vulcan" as the compatible property. The firmware has PSCI 0.2 support for cpu wakeup.
