Subject: wifi: ath11k: Send PME message during wakeup from D3cold
From: Baochen Qiang <quic_bqiang@xxxxxxxxxxx>
commit 3f9b09ccf7d5f23066b02881a737bee42def9d1a upstream.
We are seeing system stuck on some specific platforms due to
WLAN chip fails to wakeup from D3cold state.
With this flag, firmware will send PME message during wakeup
and this issue is gone.
