dmaengine: move HIGHMEM64G restriction to ASYNC_TX_DMA
On HIGHMEM64G systems dma_addr_t is known to be larger than (void *) which precludes async_xor from performing dma address conversions by reusing the input parameter address list. However, other parts of the dmaengine infrastructure do not suffer this constraint, so the HIGHMEM64G restriction can be down-levelled. Signed-off-by: Dan Williams <dan.j.williams@intel.com>
