wifi: ath12k: introduce QMI firmware ready flag
When hardware device group abstraction is introduced, the QMI firmware ready
event of different devices in a group can be received simultaneously. To
indicate the firmware ready event is completed for a particular device in a
group set a flag (ATH12K_FLAG_QMI_FW_READY_COMPLETE). This helps the upcoming
hardware recovery implementation for hardware device group abstraction.
