This causes issue with single pdev devices where firmware does not respond to the WMI/HTT request sent from host. For single pdev devices firmware expects pdev id as 1 for 5 GHz/6 GHz phy and 2 for 2 GHz band. Add wrapper ath12k_mac_get_target_pdev_id() to help fetch right pdev for single pdev devices.
