Convert the dc(4) driver to the busdma API. This is a necessary step
to have this driver working on sparc64. It still needs to be made
endian-clean before it can work there.
Special thanks to dragonk@evilcode.net for sending me a dc(4) card so
that I was able to do this work.
Many cheers to all the people that tested this change, thanks to them,
this change shouldn't break anything :-).
Tested by: marcel (i386 and ia64), ru (i386), wilko (alpha),
mbr (i386), wpaul (i386) and
Will Saxon <WillS@housing.ufl.edu> (i386)
