Convert the fxp(4) driver to the busdma API.

This patch is rather big because I had to significantly redesign
the driver to make the busdma conversion possible.  Most notably,
hardware and software structures were carefully splitted to get
rid of all the structs overlapping evilness.

Special thanks to phk and Richard Puga <puga@mauibuilt.com> for
providing me with fxp(4) hardware to do this work.

Thanks to marcel for testing this on ia64, and to Fred Clift
<fclift@verio.net> for testing this on alpha.

Tested on:	i386, ia64, alpha
