Robert Marko 789a0bac35 mac80211: ath11k: sync with ath-next 
Synchronize the ath11k backports with the current ath-next tree.

This brings in actually setting the MU-MIMO parameters in HW and 6GHz
regulatory support along with some minor resource handling fixes.

This allows to easily backport further fixes as cherry picking them has
started requiring manual conflict resolution.

Subject: [PATCH] wifi: ath11k: push MU-MIMO params from hostapd to hardware
In the previous behaviour only HE IE in management frames are changed
regarding MU-MIMO configurations and not in hardware. Adding push of
MU-MIMO configurations to the hardware as well.
Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.4.0.1-00356-QCAHKSWPL_SILICONZ-1
