Subject: [PATCH v6 3/9] PCI: endpoint: functions/pci-epf-test: Add second entry

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

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

Updates the binding documentation accordingly.

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.
Changes v4->v5:
 - Changed pci_epf_test_cfg2 to pci_epf_test_designware.
Changes v5->v6:
 - Changed name field from pci_epf_test_designware to pci_epf_test_dw.
