Log Message:
 - Fix timing settings for DMA: the controller was always set up to use
   DMA mode 0 (compatible).
 - The 2 Ultra-dma registers are in fact one 32-bit register. 
   Change the macros and setup in a way it may now work (but still untested,
   thus not enabled by default).
 - For DMA mode 1, use a more efficient timing than the one suggested
   by intel.
Some work is still needed here to get ATAPI DMA working (should be done soon).
