Bug description:
  Once r8169 (Realtek ethernet) and its root port enter to D3, plugging
  network cable doesn't wake r8169 up.

  Revert "PCI/PME: Implement runtime PM callbacks".
  Quote the original commit message:
  The commit tried to prevent root port waking up from D3cold immediately but
  looks like disabing root port PME interrupt is not the right way to fix
  that issue so revert it now.  The patch following proposes an alternative
  solution to that issue.

  After applying the fix, plugging the ethernet cable can generate PME IRQ
  correctly, hence waking up r8169.

  [Regression Potential]
  Medium. The commits are relative new, rely on some PCI detail that I am
  not familiar with (PCI spec isn't publicly available).
  Fortunately we only need this fix for Unstable/OEM-B, so it won't hit
  most users if any regression happens.
