It looks like reverting 1bde9ecf018ee646b68258921bf0fa364afda38a fixes
suspend issues when writing devices to /sys/power/pm_test, but also
reverting 6c6bc1aee6a61fe7a98196794735849286761a4a fixes suspend issues
when using standard suspend/resume:

PCI: PM: Skip devices in D0 for suspend-to-idle
BugLink: https://bugs.launchpad.net/bugs/1808957
Patchwork: https://patchwork.kernel.org/patch/10993697/
Commit d491f2b75237 ("PCI: PM: Avoid possible suspend-to-idle issue")
attempted to avoid a problem with devices whose drivers want them to
stay in D0 over suspend-to-idle and resume, but it did not go as far
as it should with that.
Namely, first of all, the power state of a PCI bridge with a
downstream device in D0 must be D0 (based on the PCI PM spec r1.2,
sec 6, table 6-1, if the bridge is not in D0, there can be no PCI
transactions on its secondary bus), but that is not actively enforced
during system-wide PM transitions, so use the skip_bus_pm flag
introduced by commit d491f2b75237 for that.
Second, the configuration of devices left in D0 (whatever the reason)
during suspend-to-idle need not be changed and attempting to put them
into D0 again by force is pointless, so explicitly avoid doing that.
