This updates mac80211 to version 5.2-rc7, this contains all the changes to the wireless subsystem up to Linux 5.2-rc7. * The removed patches are applied upstream * b43 now uses kmod-lib-cordic * Update the nl80211.h file in iw to match backports version. * Remove the two backports from kernel 4.9, they were needed for mt76, but that can use the version from backports now, otherwise they collide and cause compile errors.
