[Koba Ko]

BugLink: https://bugs.launchpad.net/bugs/2042385

[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.

[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.

[Misc]
For Unstable, built with mantic configuration
