wifi: ath12k: update EMLSR capabilities of ML Station
When EMLSR operation is enabled for an ML Station, EMLSR transition
timeout, padding delay and transition delay should be updated to
Firmware. Above parameters will be used by Firmware to do EMLSR operation
such as sending EML operation mode notification frame, initial control
frame etc.
Obtain above parameters from EML capabilities information present in
ieee80211_sta object and update the same to Firmware in peer assoc WMI
command sent for ML station.
MLO is not enabled in WCN7850 and hence this change is not applicable to
it as of now. This can be a leverage once it is enabled in future.
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.3.1-00173-QCAHKSWPL_SILICONZ-1
