hw/i386/amd_iommu: Factor amdvi_pci_realize out of amdvi_sysbus_realize

Aside the Frankenstein model of a SysBusDevice realizing a PCIDevice,
QOM parents shouldn't access children internals. In this particular
case, amdvi_sysbus_realize() is just open-coding TYPE_AMD_IOMMU_PCI's
DeviceRealize() handler. Factor it out.

Declare QOM-cast macros with OBJECT_DECLARE_SIMPLE_TYPE() so we can
cast the AMDVIPCIState in amdvi_pci_realize().

Note this commit removes the single use in the repository of
pci_add_capability() and msi_init() on a *realized* QDev instance.
