Upgrade of EIDE DMA support, Johns comments:
* lots of fixes to error handling-- mostly works now
* improve DMA timing config for Triton chipsets-- PIIX4 and UDMA drive
still untested
* generally improve DMA config in many ways-- mostly cleanup
* clean up boot-time messages
* rewrite PRD generation algorithm
* first wd timeout is now longer, to handle drive spinup
