soc/intel/xeon_sp: Attach more stacks

Attach UBOX stacks as well and thus rename the function to
attack_stacks. In order to use PCI drivers for UBOX devices,
locating UBOX devices by vendor and device IDs and replacing device
access by specifying S:B:D:F numbers, add a PCI domain for the UBOX
stacks and let the PCI enumerator index all devices.

Since there are no PCI BARs on the UBOX bus the PCI locator doesn't
have to assign resources on those buses.

Once all PCI devices on the UBOX stack can be located without knowing
their UBOX bus number and PCI segment the Xeon-SP code can fully
enable the multi PCI segment group support.

Test: ibm/sbp1 (4S) is able to find all PCU devices by PCI ID.
