wifi: ath12k: add processing for TWT enable event
When ath12k send TWT enable command to firmware, firmware will return a TWT
enable event to ath12k. Through the analysis of TWT enable event status, we
can easily obtain the status of TWT enable command. It can be more
convenient to debug TWT.
This patch works with WCN7850 and QCN9274.
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4
