  Log:
  Fix panic and breakage for non-DMA ATA devices e.g. powermac macio cells.
  Handle cases where dma function pointers may be NULL, and where
  the max_iosize can't be derived from a DMA data structure. For
  the latter, revert to the prior behaviour of using DFLTPHYS for
  the max i/o size when there is no other data.
