- Move bus dependent defines to {isa,cbus}_dmareg.h.
- Use isa/isareg.h rather than <arch>/isa/isa.h.

Tested on: i386, pc98

Since we are quite unlikely to ever face another platform which
uses the i8237 without trying to emulate the PC architecture move
the register definitions for the i8237 chip into the central include
file for the chip, except for the PC98 case which is magic.

Add new isa_dmatc() function which tells us as cheaply as possible
if the terminal count has been reached for a given channel.

Repo copy i8237.h to dev/ic so we can get rid of some of the final vestiges
of includes of i386 files from non-i386 ports.

$Id$ -> $FreeBSD$

Back out part 1 of the MCFH that changed $Id$ to $FreeBSD$. We are not
ready for it yet.

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Remove trailing whitespace.

DMA automode patch, fix SB16 clicks
Submitted by: tim@cs.city.ac.uk

Removed all patch kit headers, sccsid and rcsid strings, put $Id$ in, some
minor cleanup. Added $Id$ to files that did not have any version info, etc
