- Use malloc(9) to allocate ivhd_hdrs list. The previous assumption
that there are at most 10 IVHDs in a system is not true. A counter
example would be a system with 4 IOMMUs, and each IOMMU is related
to IVHDs type 10h, 11h and 40h in the ACPI IVRS table.
- Always scan through the whole ivhd_hdrs list to find IVHDs that has
the same DeviceId but less prioritized IVHD type.
