dmaengine: ioatdma: disable relaxed ordering for ioatdma
ioatdma by default is in snoop mode. Relaxed ordering according to spec does not do anything in snoop mode. However, it causes hang or significant performance degrade when tested with NTB. Disabling in the driver due to some BIOS do not configure it correctly. Signed-off-by: Dave Jiang <dave.jiang@intel.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
