The DMA mask on SI parts is 40 bits not 44. Looks like a copy

Fixed locally.
As I have no way to reproduce this, as the ring gfx timeout error is
logged ten seconds after the IO_PAGE_FAULT, is very likely to be related?
Hopefully I am going to be able to test this on Friday. Does AMD’s QA
team have the cards to test the `iommu.forcedac=1` case? Is that test
case going to be added to the “test protocol”?
Lastly, should a Fixes tag be added, so it’s picked up for the stable
series?
Kind regards,
Paul
