Bug description:
[Impact]
the previous commit has been SRUed that enable CONFIG_INTEL_IOMMU_DEFAULT_ON.
https://bugs.launchpad.net/subiquity/+bug/1937295
but it would caused the regression with AMD/NVIDIA GPUs.
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1965882
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1971146
[Fix]
Revert the vmd: Revert 2565e5b69c44 ("PCI: vmd: Do not disable MSI-X
remapping if interrupt remapping is enabled by IOMMU.")
Assign VMD irq domain before enumeration, irq domain comes from pci driver.
[Test Case]
1. In BIOS, change to VMD
2. Check if SKU could boot-up.
[Where problems could occur]
it reduce the affected region to only VMD.
