Merge branch 'pci/misc'

  - add macros for PCIe Link Control 2 register (Frederick Lawler)

  - replace IB/hfi1 custom macros with PCI core versions (Frederick Lawler)

  - remove dead microblaze and xtensa code (Bjorn Helgaas)

  - use dev_printk() when possible in xtensa and mips (Bjorn Helgaas)

* pci/misc:
  MIPS: PCI: Use dev_printk() when possible
  xtensa/PCI: Use dev_printk() when possible
  xtensa/PCI: Make variables static
  xtensa/PCI: Remove dead code
  microblaze/PCI: Remove pcibios_claim_one_bus() dead code
  microblaze/PCI: Remove pcibios_finish_adding_to_bus() dead code
  IB/hfi1: Replace custom hfi1 macros with PCIe macros
  PCI: Add PCI_EXP_LNKCTL2_TLS* macros
