Bug Description

[SRU Justfication]

[Impact]

Intel iommu was turned on by default in mainline build v5.15.5 or jammy
-generic kernel 5.15.0-12.12. This would breaks IPU6.

[Fix]

Use IOMMU passthrough mode for IPU6 as it has its own iommu hardware.

[Test Case]

Apply the fix and kernel should print a new info line:

  Passthrough IOMMU for integrated Intel IPU

and IPU6 camera should continue to work without intel_iommu=off
work-around.

[Where problems could occur]

No. That's what it should have been done.

[Other Info]

This only affects kernel >= 5.15, so only Jammy is nominated.

Intel IPU6 driver has been proposed for Jammy for hwe-5.15 migration in
bug 1955383
(https://lists.ubuntu.com/archives/kernel-team/2021-December/126749.html).
The port for 5.17 unstable would be filed soon. Still under discussion.

While there is no plan for Intel to upstream Intel IPU6 driver before
kernel camera API is out, these extra prerequisite patches will only be
staged in a separate patches folder in the upstream repository.

========== original bug description ==========

Intel iommu was turned on by default in mainline build v5.15.5 or jammy -generic kernel 5.15.0-12.12. This would breaks IPU6 leaving error messages:

This can be worked-around with intel_iommu=off.
