Extending I2C man pages

[Stefan Bethke]

I would appreciate if someone could review the following patch:

http://www.lassitu.de/freebsd/iic-man-page-additions.patch

It includes updated man pages for iicbb.4 and iicbus.4, and new man pages for gpioiic.4, iicbb.9, iicbus.9, and iicbus_request_bus.9.

There is a few more related drivers and functions that I think should receive man pages (sys/dev/gpio/* as well as more functions from sys/dev/iicbus/iiconf.h); I'll work on those as time permits.


Thanks,
Stefan
