[PATCH v2 01/10] PCI: update current bus speed as part of pci_bus_add_devices()

[Krishna Chaitanya Chundru]

If the link is not up till the pwrctl drivers enable power to endpoints
then cur_bus_speed will not be updated with correct speed.

As part of rescan, pci_bus_add_devices() will be called and as part of
it update the link bus speed.
