drm/amdgpu: enable watchdog feature for SQ of aldebaran
SQ's watchdog timer monitors forward progress, a mask of which waves
caused the watchdog timeout is recorded into ras status registers and
then trigger a system fatal error event.
v2:
1. change *query_timeout_status to *query_sq_timeout_status.
2. move query_sq_timeout_status into amdgpu_ras_do_recovery.
3. add module parameters to enable/disable fatal error event and modify
the watchdog timer.
v3:
1. remove unused parameters of *enable_watchdog_timer
