In order to signal to Graviton [123] systems that a device is ready
to be "ejected" (after a detach request is made via the EC2 API) we
need to set PCIM_PSTAT_PME to 1 and PCIM_PSTAT_PMEENABLE to 0. We are
not aware of any rationale for this requirement beyond "another OS
kernel happens to do this", i.e. this is effectively bug-for-bug
compatibility.
Arguably this should be done by the ACPI _EJ0 method on these systems,
but it is not.
Create a new ACPI_Q_CLEAR_PME_ON_DETACH quirk and set it in EC2 AMIs,
and add the PCI register write to acpi_pci_device_notify_handler when
that quirk is set.
