arm64: Select GENERIC_CPU_CACHE_MAINTENANCE 



The generic CPU cache maintenance framework provides a way to register
drivers for devices implementing the underlying support for
cpu_cache_has_invalidate_memregion(). Enable it for arm64 by selecting
GENERIC_CPU_CACHE_MAINTENANCE which provides the implementation for,
and in turn selects, ARCH_HAS_CPU_CACHE_INVALIDATE_MEMREGION.
