From: Sriram R <quic_srirrama@quicinc.com>

Currently, struct ieee80211_sta (sta) is used for many WMI and mac80211 ops but
for multi link station, driver should use struct ath12k_link_sta (arsta)
instead of sta. Add changes to use arsta object for WMI commands and other
mac80211 ops.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.3.1-00173-QCAHKSWPL_SILICONZ-1
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
