Mario Limonciello ce47ae8961 nvme-pci: look for StorageD3Enable on companion ACPI device instead 
[ Upstream commit e21e0243e7b0f1c2a21d21f4d115f7b37175772a ]

The documentation around the StorageD3Enable property hints that it
should be made on the PCI device.  This is where newer AMD systems set
the property and it's required for S0i3 support.

So rather than look for nodes of the root port only present on Intel
systems, switch to the companion ACPI device for all systems.
David Box from Intel indicated this should work on Intel as well.
