wifi: ath11k: Send PME message during wakeup from D3cold 

commit 3f9b09ccf7 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.

Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3
