Rafael J. Wysocki 00fd9aad55 Revert "ACPI: PM: Let acpi_dev_pm_attach() skip devices without ACPI PM" 
Revert commit 88fad6ce09 ("ACPI: PM: Let acpi_dev_pm_attach() skip
devices without ACPI PM") that introduced a SoundWire suspend regression
[1].

It is actually not true that the commit above doesn't make a functional
difference because acpi_subsys_suspend(), for example, may resume
devices in runtime-suspend which affects the subsequent handling of
those devices during the suspend transition.  For this reason, the
devices that were handled by the ACPI PM domain before that commit may
be handled differently now which may lead to suspend-resume issues.
