ARM: mm: Add strongly ordered descriptor support.
On certain architectures, there might be a need to mark certain addresses with strongly ordered memory attributes to avoid ordering issues at the interconnect level. On OMAP4, the asynchronous bridge buffers can only be drained with strongly ordered accesses and hence the need to mark the memory strongly ordered.
