'default n' can be omitted in general from interactive Kconfig

Ok, then I remove it.

perhaps add a proper dependency on iommu or swiotlb presence as well - 
in case we decide to make it all disable-able again and dont have the

No problem. But its hard to believe that we make the DMA-API
disable-able some day ;)
The best dependency in this case should be SWIOTLB I think.
