accel/ivpu: Add FW state dump on TDR
[ Upstream commit 5e162f872d7af8f041b143536617ab2563ea7de5 ]
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.
