x86: Fix iommu=soft boot option

iommu=soft boot option forces the kernel to use swiotlb.

( This has the side-effect of enabling the swiotlb over the
  GART if this boot option is provided. This is the desired
  behavior of the swiotlb boot option and works like that
  for all other hw-IOMMU drivers. )
