Merging SSB upstream

So, now that mac80211 is merged upstream, I think it's
time to merge SSB and the b44-ssb port upstream.
Note that bcm43xx-mac80211 is _not_ ready for upstream, yet.

What do you think? I'd like to merge ssb as-is, although
the embedded-device parts are not quite finished, yet.
But they don't interfere with the non-embedded parts used
by b44 and the bcm43xx PCI cards.
So we _could_ remove the ssb-mips code, but I don't like to
do that for better maintainability. It doesn't hurt anyone IMO.

Some opinions?
