x86, GART/AMD-VI: Make AMD GART and IOMMU 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]
|
+-------+--------+
/ \
[detect_calgary] [gart_iommu_hole_init]
|
[amd_iommu_detect]
Meaning that 'amd_iommu_detect' will be called after
'gart_iommu_hole_init'.
