x86, swiotlb: Make SWIOTLB use IOMMU_INIT_* macros.
We utilize the IOMMU_INIT macros to create this dependency: [pci_xen_swiotlb_detect] | [pci_swiotlb_detect_override] | [pci_swiotlb_detect_4gb] And set the SWIOTLB IOMMU_INIT to utilize 'pci_swiotlb_init' for .init and 'pci_swiotlb_late_init' for .late_init.
