Support for N-PHYs rev 3+ in b43

There are two major code paths needed to support 802.11n Broadcom devices. First is for N-PHY revisions 1 and 2, second for 3 and higher.

As the first step we implemented support for PHYs 1 and 2. However I've just published patches enabling support for revision 3 and higher. Hopefully it will be just in time for 2.6.38 :)

Such a little Christmas gift from me ;)
