[PATCH v2 0/7] acpi_build: Refactor and cleanup AMD IVRS build

QEMU reports several IVRS fields that either do not match what the
emulated AMD IOMMU actually implements, or are hardcoded and drift out
of sync with the extended feature register (EFR). This series fixes
them.

The goal is to land a maintainable baseline before adding AMD
hardware-accelerated vIOMMU support in QEMU, where we will require multiple
vIOMMUs attached to different pcie-pxb buses in order to serve set of
passthrough devices.

Please refer to AMD IOMMU spec [1] for more details about IVRS.

   feature"
 - Use pci_get_bdf() instead of pci_bus_num
 - Move AMD IVRS specific macros from acpi-build.h to amd_iommu.h
 - Remove GLX_SUP from feature reporting field
