armv8: add hooks for all cache-wide operations
SoC-specific logic may be required for all forms of cache-wide
operations; invalidate and flush of both dcache and icache (note that
only 3 of the 4 possible combinations make sense, since the icache never
contains dirty lines). This patch adds an optional hook for all
implemented cache-wide operations, and renames the one existing hook to
better represent exactly which operation it is implementing. A dummy
no-op implementation of each hook is provided.
