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

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.
