Dave Jiang 511deae026 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.
