async_tx: remove HIGHMEM64G restriction
This restriction prevented ASYNC_TX_DMA from being enabled on platform configurations where DMA address conversion could not be performed in place on the stack. Since commit 04ce9ab3 ("async_xor: permit callers to pass in a 'dma/page scribble' region") the async_tx api now either uses a caller provided 'scribble' buffer, or performs the conversion in place when sizeof(dma_addr_t) <= sizeof(struct page *).

This allows the async_tx api to take advantage of offload engines for
memcpy, memset, xor, and raid6 p+q operations. If your platform has
