Subject: [PATCH v2 0/2] PCI: endpoint: Fix core_init_notifier feature

This series has two fixes for core_init_notifier feature.

Fix the bug that the driver can't register its notifier function
if core_init_notifier == true and linkup_notifier == false.

If enabling the controller is delayed due to core_init_notifier, 
accesses to the controller register should be avoided rather than
enabling the controller.

Changes since v1:
- Add Acked-by and Reviewed-by lines

Kunihiko Hayashi (2):
  PCI: endpoint: pci-epf-test: register notifier if only
    core_init_notifier is enabled
  PCI: designware-ep: Fix the access to DBI/iATU registers before
    enabling controller
