hw/i386/amd_iommu: Allow migration when explicitly create the AMDVI-PCI device

Browse source 
Add migration support for AMD IOMMU model by saving necessary AMDVIState
parameters for MMIO registers, device table, command buffer, and event
buffers.

Also change devtab_len type from size_t to uint64_t to avoid 32-bit build
issue.
