mac80211: Update to version 5.2-rc7

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.

-Subject: [PATCH] mac80211: minstrel: fix sampling/reporting of CCK rates
- in HT mode
-
-Long/short preamble selection cannot be sampled separately, since it
-depends on the BSS state. Because of that, sampling attempts to
-currently not used preamble modes are not counted in the statistics,
-which leads to CCK rates being sampled too often.
-
-Fix statistics accounting for long/short preamble by increasing the
-index where necessary.
-Fix excessive CCK rate sampling by dropping unsupported sample attempts.
-
-This improves throughput on 2.4 GHz channels
