wifi: ath11k: Add cold boot calibration support on WCN6750
Add cold boot calibration support on WCN6750. Unlike other
chipsets where firmware(FW) is restarted after cold boot
calibration is completed, it is recommended not to restart
the firmware for WCN6750.
For WCN6750, FW sends both CAL_DONE & FW_READY QMI indication
to the driver after cold boot calibration is completed.
QMI message flow for WCN6750 with cold boot support:
FW_INIT_DONE to HOST -> CALIBRATION Mode to FW -> CAL_DONE to Host ->
FW_READY to Host -> MODE_ON to FW
QMI message flow for other chipsets with cold boot support:
FW_INIT_DONE to Host -> CALIBRATION Mode to FW -> FW_READY to Host ->
Trigger FW restart -> FW_INIT_DONE to HOST -> MODE_ON to FW
QMI message flow for chipsets without cold boot support:
FW_INIT_DONE to Host -> MODE_ON to FW
Tested-on: WCN6750 hw1.0 AHB WLAN.MSL.1.0.1-00887-QCAMSLSWPLZ-1
