[PATCH] ACPI: PM: Revert "ACPI / PM: Blacklist Low Power S0 Idle _DSM for Dell XPS13 9360"

[Mario Limonciello]

This reverts part of
commit 71630b7a832f ("ACPI / PM: Blacklist Low Power S0 Idle _DSM for Dell XPS13 9360")
to remove the S0ix blacklist for the XPS 9360.

The problems with this system occurred in one possible NVME SSD when
putting system into s0ix.  As the NVME sleep behavior has been adjusted
in d916b1be this is expected to be now resolved.

The particular failing configuration was reported by only ever failed for Paul Menzel, so hopefully
he can test on his failing system.

1.  Please add, that it was the Hynix(?) SSD.
2.  Please add the commit message summary of d916b1be.

     nvme-pci: use host managed power state for suspend

Tag it for the stable series? d916b1be (first tag v5.3-rc1) is not 
tagged for stable.

I successfully tested Linux 5.4-rc1+ with this commit last Friday on the 
Dell XPS 13 9360.

Tested-by: Paul Menzel <pmenzel@molgen.mpg.de>

Kind regards,

Rafael, let me know if you want me to adjust the commit message and resubmit
or if you would just handle this task.

Although Dell arranged a lot of testing with partners I don't feel d916b1be is a stable
candidate.  Rafael found a corner case with regards to ASPM configuration last minute
in 5.3rcX, I found a another corner case related to order of events and timing around
PC10 entry that's getting fixed in 5.4.

Well that's great, appreciate your testing and confirmation.
