[Fix] 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. " [Test] 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.
