Enable Subsystem Restart test support.
Clients can trigger SSR through debugfs as follows:

echo <trigger_val> > /d/msm_vidc/core/trigger_ssr

u64 trigger_val provides:
  /* <test_addr><sub_client_id><ssr_type>
   * ssr_type: 0-3 bits
   * sub_client_id: 4-7 bits
   * reserved: 8-31 bits
   * test_addr: 32-63 bits */
