ARM: cacheflush: use -ishst dsb variant for ensuring flush completion
flush_cache_vmap contains a dsb to ensure that any cacheflushing operations to flush out newly written ptes have completed. This patch adds the -ishst option to the dsb, since that is all that is required for completing cacheflushing in the inner-shareable domain. Signed-off-by: Will Deacon <will.deacon@arm.com>
