Subject: MIPS: PCI: add controllers before the specified head

With commit 23dac14d058f ("MIPS: PCI: Use struct list_head lists") new
controllers are added after the specified head where they were added
before the specified head previously.

Use list_add_tail to restore the former order.

This patches fixes the following PCI error on lantiq:

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