changed register for start of dma buffer to be DD_NEXT_INITBUF instead
...
of DD_NEXT for regular dma transfers, and not just ethernet transmit.
Keep track of dma read/write direction and set it each time we start or
restart dma. This allows scsi to work, and doesn't appear to hinder ethernet.

Sync'ed more files and routines with mvme port in prepartion for UVM.

Commented out some bus_dma code, until I can fix.
...
(bus_dma.c needs sync with alpha port!)
Continued progress on scsi driver.
A couple of other compiler warning level of tweaks.

changed diagnostic panic into a printf since an unexpected condition appears
...
to happen every once in a while. (The DMA interrupt gets called w/o
the completed bit set)
