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 Submitted by: John Hood <cgull@smoke.marlboro.vt.us>
