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.
