Adds a seconds entry on the pci_epf_test_ids structure that disables the
linkup_notifier parameter on driver.

This allows EPs that doesn't have linkup notification signal to work
with pcitest.

Change v2->v3:
 - Added second entry in pci_epf_test_ids structure.
 - Remove test_reg_bar field assignment on second entry.
Changes v3->v4:
- Nothing changed, just to follow the patch set version.

I'd prefer this to be named pci_epf_test_designware so that configfs entry is
self explanatory.

Thanks

Please document the new epf binding in
