Merge branch 'pci/devres'

- Update resource request API documentation to encourage callers to supply
  a driver name when requesting resources (Philipp Stanner)

- Export pci_intx_unmanaged() and pcim_intx() (always managed) so callers
  of pci_intx() (which is sometimes managed) can explicitly choose the one
  they need (Philipp Stanner)

- Convert drivers from pci_intx() to always-managed pcim_intx() or
  never-managed pci_intx_unmanaged(): amd_sfh, ata (ahci, ata_piix,
  pata_rdc, sata_sil24, sata_sis, sata_uli, sata_vsc), bnx2x, bna, ntb,
  qtnfmac, rtsx, tifm_7xx1, vfio, xen-pciback (Philipp Stanner)

- Remove pci_intx_unmanaged() since pci_intx() is now always unmanaged and
  pcim_intx() is always managed (Philipp Stanner)
