- Request the PCI BAR used by xboxvideo (Philipp Stanner)

- Export pcim_iomap_region() and deprecate pcim_iomap_regions() (Philipp
  Stanner)

- Request and map drm/ast BARs with pcim_iomap_region() (Philipp Stanner)

* pci/devres:
  drm/ast: Request PCI BAR with devres
  PCI: Deprecate pcim_iomap_regions() in favor of pcim_iomap_region()
