[PATCH v2 5/8] arm64: Select GENERIC_CPU_CACHE_INVALIDATE_MEMREGION

[Jonathan Cameron]

Also ensure the hooks that the generic cache framework uses
are available by selecting ARCH_HAS_CPU_CACHE_INVALIDATE_MEMREGION.

The generic CPU cache framework registers a callback which
iterates over any registered cache coherency drivers to perform
the requested flush.
