Revert "ACPI/PCI: Pay attention to device-specific _PXM node values"

This reverts commit bad7dcd9.

bad7dcd9 ("ACPI/PCI: Pay attention to device-specific _PXM node
values") caused boot failures (no console output at all) for Martin [1]
and Ingo [2] on AMD ThreadRipper systems.

Revert the commit until we figure out how to safely use these
device-specific _PXM values.
