This bug is awaiting verification that the linux-oem-6.5/6.5.0-1008.8
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-6.5' to 'verification-done-
jammy-linux-oem-6.5'. If the problem still exists, change the tag
'verification-needed-jammy-linux-oem-6.5' to 'verification-failed-jammy-
linux-oem-6.5'.

Bug description:
  [Impact]
  RPL-U CPU C-state alway keep at C3 when system run PHM with idle screen on.

  [Fix]
  Realtek r8168h/r8111's ASPM is blocked due to users report the regression on 
their platform[0].
  Add quirks for some Dell Platforms to enable ASPM and allow RPL-U sleep 
deeper.

  [0], https://bugzilla.kernel.org/show_bug.cgi?id=217814

  [where the issue could happen]
  Medium, may have the regression but the risk is limited in some Dell 
platforms.
  we will ask Realtek's effort once the regression is observed.
