icnss2: Send rf_subtype to firmware via QMI command

Send rf_subtype based on dt node "qcom, rf_subtype" to
firmware using QMI_WLFW_WLAN_HW_INIT_CFG message after
qmi server arrive. Firmware will initialize different
halphy code based on rf_subtype sent by host.
Currently, this change will be applicable only for
adreastea targets which can have either slate RF or Apache
RF attached.
