Jacek Lawrynowicz 27d19268cf accel/ivpu: Improve recovery and reset support
- Synchronize job submission with reset/recovery using reset_lock
  - Always print recovery reason and call diagnose_failure()
  - Don't allow for autosupend during recovery
  - Prevent immediate autosuspend after reset/recovery
  - Prevent force_recovery for issuing TDR when device is suspended
  - Reset VPU instead triggering recovery after changing debugfs params
