PCI: Consolidate PCI DMA constants and interfaces in linux/pci-dma-compat.h
Christoph added a generic include/linux/pci-dma-compat.h, so now there's
one place with most of the PCI DMA interfaces. Move more PCI DMA-related
things there:
- The PCI_DMA_* direction constants from linux/pci.h
- The pci_set_dma_max_seg_size() and pci_set_dma_seg_boundary()
CONFIG_PCI implementations from drivers/pci/pci.c
- The pci_set_dma_max_seg_size() and pci_set_dma_seg_boundary()
!CONFIG_PCI stubs from linux/pci.h
- The pci_set_dma_mask() and pci_set_consistent_dma_mask()
!CONFIG_PCI stubs from linux/pci.h
