[ARM] Don't call consistent_sync() for DMA coherent memory Memory allocated by the coherent memory allocators will be marked uncacheable, which means it's pointless calling consistent_sync() to perform cache maintainence on this memory; it's just a waste of CPU cycles. Moreover, with the (subsequent) merge of outer cache support, it actually breaks things to call consistent_sync() on anything but direct-mapped memory.
