iwi(4) update

[Johannes Hofmann <johannes.hofmann@xxxxxx>]

Hi,

in http://gitweb.dragonflybsd.org/~hofmann (branch iwi) is an update
for iwi(4) to make it work with the new WLAN framework.
It includes the firmware blobs and makefiles to build firmware
modules.
It works fine so far on my UP laptop.

Cheers,
Johannes

PS: I hope I got the git stuff right....
