ArmPlatformPkg/ArmVExpressDxe: Platform specific driver for ARM VExpress based platform

This driver should be used when adding code specific to a platform based on ARM VExpress based board. ArmFvpDxe driver has been renamed into ArmVExpressDxe driver to support the hardware based platforms and the model based platforms.
