[PATCH v2] MIPS: PCI: scan PCI controllers in reverse order

Commit 23dac14d058f ("MIPS: PCI: Use struct list_head lists") changed
the controller list from reverse to straight order without taking care
of the changed order for the scan of the recorded PCI controllers.

Traverse the list in reverse order to restore the former behaviour.

This patches fixes the following PCI error on lantiq:

  pci 0000:01:00.0: BAR 0: error updating (0x1c000004 != 0x000000)
