Using the DMC wakelock is the official recommendation for Xe3_LPD. This
series apply fixes to the current DMC wakelock implementation and
enables it by default for Xe3_LPD. The series has been tested with a PTL
machine.

This is the v4 of the series. The only difference from v3 is that I decided to
drop patches related to the usage of HAS_DMC() in HAS_DMC_WAKELOCK(), as they
might need more polishing and will be send as a separate series. I believe we
don't need to be blocked on those to get this series landed.
