AMD {SoC, AGESA, binaryPI}: Don't use both of _ADR and _HID
PCI devices starting from 18 are processor configuration devices for each
node and are not a bus itself.
According to ACPI specification 6.3 section 6.1.5:
"... _HID object must be used to describe any device that will be
enumerated by OSPM. OSPM only enumerates a device when no bus enumerator
can detect the device ID. ... Use the _ADR object to describe devices
enumerated by bus enumerators other than OSPM."
PCI device 18 with its functions has a standard enumerator, which is PCI
enumerator so it needs a _ADR. Create a separate ACPI device for the
processor configuration space. This fixes the ACPI compliance problem
from CB:36318.
