    PCI: remove PCI_DMA_BUS_IS_PHYS · 325ef185

    This was used by the ide, scsi and networking code in the past to
    determine if they should bounce payloads.  Now that the dma mapping
    always have to support dma to all physical memory (thanks to swiotlb
    for non-iommu systems) there is no need to this crude hack any more.
