[Joseph Salisbury]

BugLink: https://bugs.launchpad.net/bugs/2049922

[Impact]

* Request from Google to include Intel patches for IDPF support if used from
out-of-tree module to prevent system instability.

Also being requested in focal:linux-gcp.  However, focal:linux-gcp
required a different backport, so it will be sent separatly.

[Fixes]
f18b1137d38c ("PCI: Extract ATS disabling to a helper function")
a18615b1cfc0 ("PCI: Disable ATS for specific Intel IPU E2000 devices")

[Test Case]

* Compile test
* Boot test
* Test on non-IDPF instance
* Also tested by Google.

[Where things could go wrong]

* Low chance of regression, changes very isolated

[Other Info]

* SF #00376470
