accel/ivpu: Add FW state dump on TDR
Send JSM state dump message at the beginning of TDR handler. This allows
FW to collect debug info in the FW log before the state of the NPU is
lost allowing to analyze the cause of a TDR.
Wait a predefined timeout (10 ms) so the FW has a chance to write debug
logs. We cannot wait for JSM response at this point because IRQs are
already disabled before TDR handler is invoked.
