Hauke Mehrtens 0b2c42ced2 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] ath10k: Don't initialize devices asynchronously
OpenWrt requires all PHYs to be initialized to create the configuration files
during bootup. ath10k violates this because it delays the creation of the PHY
to a not well defined point in the future.
Forcing the work to be done immediately works around this problem but may also
delay the boot when firmware images cannot be found.
