broadcom_sta: Add patch for supporting Linux 4.7

Patch is from Arch Linux at:

https://aur.archlinux.org/cgit/aur.git/tree/?h=broadcom-wl

I've tested building against 3.18.36, 4.4.16 and 4.7.0.

+Since Linux 4.7, the enum ieee80211_band is no longer used
+
+This shall cause no problem's since both enums ieee80211_band
+and nl80211_band were added in the same commit:
+https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit?id=13ae75b103e07304a34ab40c9136e9f53e06475c
+
+This patch refactors the references of IEEE80211_BAND_* to NL80211_BAND_*
