hw/riscv/virt: Add the BDF of IOMMU to RISCVVirtState structure

When the IOMMU is implemented as a PCI device, its BDF is created
locally in virt.c. However, the same BDF is also required in
virt-acpi-build.c to support ACPI. Therefore, make this information part
of the global RISCVVirtState structure so that it can be accessed
outside of virt.c as well.
