Currently, only the EHT IE in management frames is updated with
respect to MU-MIMO configurations, but this change is not
reflected in the hardware. Add support to propagate MU-MIMO
configurations to the hardware as well for AP mode. Similar
support for STA mode will be added in future.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1

A couple of your patches, including this one, have subjects that refer to
hostapd. The driver should operate agnostic of the userpace entities that are
managing it, so please avoid referring to a specific userspace entity.

Describe the problem in terms of the operation being performed, not the entity
that is initiating the operation.
