* RETURN: Status
*
* DESCRIPTION: This function derives a full PCI ID for a PCI device,
* consisting of a Segment number, Bus number, Device number,
* and function code.
*
* The PCI hardware dynamically configures PCI bus numbers
* depending on the bus topology discovered during system
* initialization. This function is invoked during configuration
* of a PCI_Config Operation Region in order to (possibly) update
* the Bus/Device/Function numbers in the pci_id with the actual
* values as determined by the hardware and operating system
* configuration.
*
* The pci_id parameter is initially populated during the Operation
* Region initialization. This function is then called, and is
* will make any necessary modifications to the Bus, Device, or
* Function number PCI ID subfields as appropriate for the
* current hardware and OS configuration.
*
* NOTE: Created 08/2010. Replaces the previous OSL acpi_os_derive_pci_id
* interface since this feature is OS-independent. This module
* specifically avoids any use of recursion by building a local
* temporary device list.
