BugLink: https://bugs.launchpad.net/bugs/1928694 [Impact] Current AMD C-state quirk is hardcoded, replace it with a better upstream version. [Fix] Sort the C-state latency value to ensure deeper C-state always has larger value. [Test] Suspend the laptop. S2idle still works with the new patch. [Where problems could occur] This is specific to AMD s0ix platforms. The new fix is effectively the same as the old one, so there's no actual behavioral change.
