Gnome doesn't run smooth when performing normal usage with RPL-P CPU

[AceLan Kao]

[Impact]
Gnome desktop doesn't run smooth when performing normal usage, the cursor usually stops working and stuck, and then becomes back to normal.

[Fix]
Can't reproduce this issue with drm-tip kernel, so found below commit after bisected
dc73ac63e63a drm/i915/rpl-p: Add stepping info

[Test]
Verified on the RPL-P machine and the cursor/window move smoothly.

[Where problems could occur]
Adding info for new RPL-P chipset should be pretty safe.

This bug is awaiting verification that the linux-oem-6.0/6.0.0-1009.9 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' to 'verification-done-jammy'. If the problem still exists, change the tag 'verification-needed-jammy' to 'verification-failed-jammy'.

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!
