pci-swiotlb-xen: Add glue code to setup dma_ops utilizing xen_swiotlb_*
functions.
We add the glue code that sets up a dma_ops structure with the
xen_swiotlb_* functions. The code turns on xen_swiotlb flag
when it detects it is running under Xen and it is either
in privileged mode or the iommu=soft flag was passed in.
It also disables the bare-metal SWIOTLB if the Xen-SWIOTLB has
been enabled.
Note: The Xen-SWIOTLB is only built when CONFIG_XEN is enabled.
