wifi: ath12k: create a structure for WMI vdev up parameters

Host needs to send multiple BSSID configurations to firmware for
each vdev in ath12k_wmi_vdev_up() for AP mode. This function accepts
individual input parameters hence any new argument will require changes
to all callers. Most of these will use default value (0 or NULL).
Create a structure for the function arguments and include objects with
all members initialized to zero to minimize future changes.
