remoteproc: qcom_q6v5_mss: Fix MDM9607 subsystem control instance ID

Browse Source 
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.
