On MDM9607, the modem firmware exposes the QMI subsystem control service
with instance ID 0x22 (34), as visible e.g. with qrtr-lookup:
$ qrtr-lookup
Service Version Instance Node Port
43 2 34 3 1 Subsystem control service
Currently, qcom_q6v5_mss uses ssctl_id 0x12 for all platforms. The QMI
service never shows up with this ID, leading to the following error when
trying to shutdown the modem:
qcom-q6v5-mss 4080000.remoteproc: timeout waiting for ssctl service
Set the correct ssctl_id to allow clean shutdown of the modem firmware with
the subsystem control service. ssctl_id 0x22 is also used by other
modem-only Qualcomm platforms in qcom_q6v5_pas, such as SDX55.
