Fix ADL: System enabled AHCI can't get into s0ix when attached ODD

This bug is awaiting verification that the linux-oem-6.1/6.1.0-1024.24 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-jammy-linux-oem-6.1' to 'verification-done-jammy-linux-oem-6.1'. If the problem still exists, change the tag 'verification-needed-jammy-linux-oem-6.1' to 'verification-failed-jammy-linux-oem-6.1'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
