[PATCH v2 09/13] ath10k: split wmi_cmd_init path

Due to API differences in initialization structures for
main and 10.x firmwares we need to split the wmi_init_cmd
and wmi_resource_config structures.
This will be usefull also when setting the correct TARGET values,
like: number of peers, vdevs, pdevs etc.
