MIPS: pci-legacy: remove busn_resource field 

No drivers set the busn_resource field in the pci_controller struct.
Commit 7ee214b540 ("MIPS: PCI: Remove unused busn_offset") almost
removed it over 3 years ago. Remove it for good to free up memory and
eliminate messages like:
  pci_bus 0000:00: root bus resource [??? 0x00000000 flags 0x0]
