So, to support coldboot calibration in QCN9074 ATH11K_COLD_BOOT_FW_RESET_DELAY extended to 60 seconds. To avoid code redundancy, fwreset_from_cold_boot moved to QMI and made common for both ahb and pci. Coldboot calibration is enabled only in FTM mode for QCN9074. QCN9074 requires firmware restart after coldboot, hence enable cbcal_restart_fw in hw_params. This support can be enabled/disabled using hw params for different hardware. Currently it is not enabled for QCA6390.
