arm: dma-mapping: flush highmem mappings
DMA allocations with no kernel mapping are likely
protected as well. Stale highmem mappings in such cases
with cache-able attributes may lead to speculative fetch
,as highmem mappings are not cleared out.
Hence flush out unused highmem mappings explicitly when
allocation request with no kernel mapping is requested.
