x86, xen-swiotlb: Make Xen-SWIOTLB use IOMMU_INIT_* macros.
We utilize the IOMMU_INIT macros to create this dependency:
[null] | [pci_xen_swiotlb_detect] | [pci_swiotlb_detect_override] | [pci_swiotlb_detect_4gb] In other words, we set 'pci_xen_swiotlb_detect' to be the first detection to be run during start.
