dma-mapping: alpha: use include/linux/pci-dma-compat.h
This converts Alpha to use include/linux/pci-dma-compat.h. Alpha is the only architecutre that implements the PCI DMA API in the own way. That makes it difficult to implement the generic DMA API via the PCI bus specific DMA API. The generic DMA API calls the PCI DMA API implementation in arch/alpha/kernel/pci_iommu.c on non Jensen systems. It calls the DMA API in arch/alpha/kernel/pci-noop.c on Jensen systems.
