pci: Let pci_dma_rw() take MemTxAttrs argument
Let devices specify transaction attributes when calling pci_dma_rw(). Keep the default MEMTXATTRS_UNSPECIFIED in the few callers. Reviewed-by: Klaus Jensen <k.jensen@samsung.com> Signed-off-by: Philippe Mathieu-Daudé <philmd@redhat.com> Message-Id: <20211223115554.3155328-10-philmd@redhat.com>
