[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.

    latency when not conformance with s0ix"
