Then generalize the acpi helper to a generic one checking ACPI and
DT and specify a proper DT binding.

If th requirement to put all devices into D3 is a plaform propery
a specific driver is always the wrong place for it.

Again, this all belongs into core code.  The nvme driver is just
a consumer of this information, just like for example the AHCI
driver.
