gpu: nvgpu: set preempt timeout
-For Si platforms, gk20a_get_gr_idle_timeout returns
3000 ms i.e. 3 sec. Currently this time is used for
preempt polling and this conflicts with channel
timeout if polling times out. Use fifo_eng_timeout_us converted
to ms for preempt polling.
-In case of preempt timeout, do not issue recovery
for si platform. ctxsw timeout will trigger recovery
if needed. For non si platforms, issue preempt timeout rc
if preempt times out.
