Improvements in b43 for N-PHY rev 3+

Earlier tests have shown we can not transmit on OFDM rates in case of 14e4:432b (PHY rev 4). Fortunately fix was really easy, we were just missing static tables for higher revisions. Adding it allowed TX on 54M rate, 11M is not maximum anymore :)

Chart compares unpatched b43 with patched one and with wl. We are still slower than wl, but at least we can reach speeds around 15M :)
