- Save L1 PM Substates Capability across suspend/resume so L1SS keeps
working after resume (Vidya Sagar)
- If device lacks L1 PM Substates Capability, don't read junk and treat it
as such a Capability (Bjorn Helgaas)
- Fix the LTR_L1.2_THRESHOLD computation, which previously configured the
threshold for entering L1.2 to be lower than intended, so L1.2 could be
used when it shouldn't be (Bjorn Helgaas)
