[PATCH v2 00/16] hw/i386/pc: Remove deprecated 2.8 and 2.9 PC machines

[Thomas Huth <thuth@redhat.com>]

The -2.8 and -2.9 machine types of the i440fx and q35 machines are
older than 6 years, so according to our support policy we can remove
them, together with a lot of the compatibility knobs that they were
using.

This is a respin of Philippe's original series here:

 https://lore.kernel.org/qemu-devel/20250501210456.89071-1-philmd@linaro.org

The following three patches still need a review:

- hw/pci/pcie: Remove QEMU_PCIE_EXTCAP_INIT definition
- hw/i386/x86-iommu: Remove X86IOMMUState::pt_supported field
- tests/qtest/test-x86-cpuid-compat: Remove the test with the i440fx-2.9 machine

Changes in v2:

- Rebased all patches to current master, and fixed the contextual conflicts
- Added Igor's Reviewed-bys
- Dropped the "hw/southbridge/ich9: Remove ICH9_LPC_SMI_F_BROADCAST_BIT
  definition" patch since the code is still required (the guest can decide
  whether to use this feature or not)
- Dropped the two "hw/nvram/fw_cfg" patches since Igor mentioned that it
  still might be useful to keep this configuration knob
- Fix "hw/pci/pcie: Remove QEMU_PCIE_EXTCAP_INIT definition" according to
  Igor's review
- Adjusted "hw/i386/x86-iommu: Remove X86IOMMUState::pt_supported field":
  The problematic hunk has already been merged in upstream, so I dropped
  it from this patch.
- Added the final patch to drop a qtest that required this machine
