This change sets the PCI devices' initial DMA capabilities conservatively and promotes them at the request of the driver, as opposed to assuming advanced DMA capabilities. The old design runs the risk of breaking drivers that assume default capabilities. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>
