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
