MFC r267021:

FreeBSD, historically, has always used 8-bit addresses for i2c devices
(7-bit device address << 1), always leaving the room for the read/write
bit.

This commit convert ti_i2c and revert r259127 on bcm2835_bsc to make them
compatible with 8-bit addresses. Previous to this commit an i2c device
would have different addresses depending on the controller it was attached
to (by example, when compared to any iicbb(4) based i2c controller), which
was a pretty annoying behavior.

Also, update the PMIC i2c address on beaglebone* DTS files to match the
new address scheme.

Now the userland utilities need to do the correct slave address shifting
(but it is going to work with any i2c controller on the system).

MFC r267834:

Clarify the expected usage of I2C 7-bit slave addresses on ioctl(2)
interface.

While here add the cross reference to iic(4) on iicbus(4).

Fix typo in comment.

Teach iic(4) the 'repeated start' I2C condition. This will be used by the
upcoming i2c(8) diag utility.

Mostly re-write man page to reflect current state of this interface.
Warn of races.

# Doc police: Please review

Mechanically kill hard sentence breaks and double whitespaces.

mdoc(7) police: removed HISTORY info from the .Os call.

mdoc(7) police: remove extraneous .Pp before and/or after .Sh.

mdoc(7) police: normalize .Nd.

Prepare for mdoc(7)NG.

Remove single-space hard sentence breaks. These degrade the quality
of the typeset output, tend to make diffs harder to read and provide
bad examples for new-comers to mdoc.

First round of config related changes to the manpages.

device blah0 -> device blah for PCI devices and busses.

$Id$ -> $FreeBSD$

Various man page cleanup:

- Sort xrefs
- FreeBSD.ORG -> FreeBSD.org
- Be consistent with section names as outlined in mdoc(7).
- Other misc mdoc cleanup.

PR: doc/13144
Submitted by: Alexey M. Zelkin <phantom@cris.net>

Add $Id$, to make it simpler for members of the translation teams to
track.

The $Id$ line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;

.\" $Id$
.\"

If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.
