From: Karthikeyan Periyasamy <quic_periyasa@quicinc.com>

When hardware device group abstraction is introduced, QMI firmware
ready event of different devices in a group can be received simultaneously.

To indicate firmware ready event is completed for a particular device in a
group set a flag (ATH12K_FLAG_QMI_FW_READY_COMPLETE). This would be
helpful when hardware recovery is introduced for hardware device group
abstraction.

Add changes to set/unset ATH12K_FLAG_QMI_FW_READY_COMPLETE flag for a
device.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4
