wifi: ath11k: Add coldboot calibration support for QCN9074
QCN9074 supports 6 GHz, which has increased number of channels
compared to 5 GHz/2 GHz. 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.
Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.7.0.1-01744-QCAHKSWPL_SILICONZ-1
