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] mwl8k: Fix rate_idx underflow
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-It was reported on OpenWrt bug tracking system[1], that several users
-are affected by the endless reboot of their routers if they configure
-5GHz interface with channel 44 or 48.
-
-The reboot loop is caused by the following excessive number of WARN_ON
-messages:
-
- WARNING: CPU: 0 PID: 0 at backports-4.19.23-1/net/mac80211/rx.c:4516
-                             ieee80211_rx_napi+0x1fc/0xa54 [mac80211]
-
-as the messages are being correctly emitted by the following guard:
-
- case RX_ENC_LEGACY:
-      if (WARN_ON(status->rate_idx >= sband->n_bitrates))
-
-as the rate_idx is in this case erroneously set to 251 (0xfb). This fix
-simply converts previously used magic number to proper constant and
-guards against substraction which is leading to the currently observed
-underflow.
-
-1. https://bugs.openwrt.org/index.php?do=details&task_id=2218
-
-Fixes: 854783444bab ("mwl8k: properly set receive status rate index on 5 GHz receive")
