x86: amd_iommu: Convert amd_iommu_detect() to use iommu_init hook
This changes amd_iommu_detect() to set amd_iommu_init to iommu_init hook if amd_iommu_detect() finds the AMD IOMMU. We can kill the code to check if we found the IOMMU in amd_iommu_init() since amd_iommu_detect() sets amd_iommu_init() only when it found the IOMMU.
