x86/amd-iommu: Fix PCI hotplug with passthrough mode
The device change notifier is initialized in the dma_ops initialization path. But this path is never executed for iommu=pt. Move the notifier initialization to IOMMU hardware init code to fix this. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
