Subject: [PATCH v3 2/2] Revert "ACPI: PM: Block ASUS B1400CEAE from suspend to idle by default"

This reverts commit d52848620de00cde4a3a5df908e231b8c8868250, which
was originally put in place to work around a s2idle failure on this
platform where the NVMe device was inaccessible upon resume.

After extended testing, we found that the firmware's implementation of
S3 is buggy and intermittently fails to wake up the system. We need
to revert to s2idle mode.

The NVMe issue has now been solved more precisely in the commit titled
"PCI: Disable D3cold on Asus B1400 PCI-NVMe bridge"
