Patches 1-4:
Fix tests so that devices do not use non-zero slots on the pcie root
ports. PCIE ports only have one slot, so PCIE devices can only be
plugged into slot 0 on a PCIE port.
Patch 5:
Enforce only one slot on PCIE port.
The test fixes must be applied before the QEMU change that checks for use
of a single slot in PCIE port.

Changelog:
v3: tags added. reword the error description in patch 5. Reword commit log in patch 4.
v2: add hd-geo-test fix as well as the actual QEMU code fix to the patchset.
The patches are added in the right order.

We are going to fix bio-tables-test in the next patch and hence need to
make sure the acpi tests continue to pass.

PCIE ports only have one slot, slot 0. Hence, non-zero slots are not available
for PCIE devices on PCIE root ports. Fix test_acpi_q35_tcg_no_acpi_hotplug()
so that the test does not use them.

Some fixes were committed in bios-tables-test in the previous commit. Update
the acpi blob and clear bios-tables-test-allowed-diff.h so that the test
continues to pass with the changes in the bios-tables-test.
Following is the asl diff between the old and the newly updated blob:

The test attaches both a SCSI controller and a pcie-to-pci bridge on the same
pcie-root-port. This is incorrect since only one downstream device can be
attached to a pcie-root-port. Further, in the test scenario, there is no need
to attach a pcie-root-port to the root complex. A SCSI controller can be
attached to a pcie-to-pci bridge which in turn can be directly attached to the
root bus (peie.0). Fix the test and simplify it.

PCI Express ports only have one slot, so PCI Express devices can only be
plugged into slot 0 on a PCIE port. Enforce it.
