acpihp does not work with some common guest kernels
Description of problem:
for pc-q35 6.1, 7.2, any guest kernel with `ACPI: Core revision` < 20230331, can not hot plug the nvidia GPUs.
So basically only guest kernel >= 6.5 can make it work so far.
But majority of server kernels are still at 4.18, 5.x. I wonder if it possible to be fixed?
I also don't know is this qemu bug? bios bug? or actually ACPIA's bug?

journal -k report error like following:
```

Nov 11 17:53:00 VMTEST kernel: nvidia: probe of 0000:08:00.0 failed with error -1
```
Steps to reproduce:
1. run the instance as I described above
2. in qemu monitor: device_add vfio-pci,host=0000:06:00.0,id=gpu0,bus=pci.8
3. login to the vm console then nvidia-smi to see the failure

workaround:
`ICH9-LPC.acpi-pci-hotplug-with-bridge-support=off` to disable the acpihp then pciehp can make it work.
