Taking some inspiration from the arch/arm code, implement the
arch-specific side of the DMA mapping ops using the new IOMMU-DMA layer.
Since there is still work to do elsewhere to make DMA configuration happen
in a more appropriate order and properly support platform devices in the
IOMMU core, the device setup code unfortunately starts out carrying some
workarounds to ensure it works correctly in the current state of things.

Sorry, I reviewed this patch before but forgot to ack it, so here it is:

Thanks! Although it turns out I'm at least partly to blame there - you
did give a reviewed-by on v5, but I didn't add it here since I'd made
significant changes - I should have checked and called that out, my bad.
(and I'm fined for the arm64 patches here to go in via the iommu tree)
I assume part of this patch will disappear at some point when the device
probing order is sorted.
I'll be working on that for 4.5, indeed. Getting the initialisation
order sorted out also stands in the way of converting 32-bit to the
common ops, so it's very high up my priority list.
Robin.
