[PATCH] pci: Iterate over busses using uclass_foreach_dev_probe

Iterate over busses using uclass_foreach_dev_probe() instead of ad-hoc
loop. The uclass_get_device_by_seq(UCLASS_PCI, busnum, &bus) == 0 in
the ad-hoc loop would break on first controller that does not link up
in its .probe() function, which is undesired, as it prevents listing
of PCIe devices on other controllers. Using uclass_get_device_by_seq()
mitigates that problem, and, at the same time, simplifies the code.
