This file seems a little inconsistent...

- Two of the TI device IDs are defined in pci_ids.h and only used in pci_endpoint_test.c
- One of the TI device IDs are defined in pci_endpoint_test.c and only used there
- The Freescale device ID is hardcoded and only used in pci_endpoint_test.c

The header in pci_ids.h has a comment suggestion definitions are only added where used
in multiple files - yet I don't think this holds true.
Bjorn - do you have a suggestion?
