If this is just for the SMU, maybe it would be better to add a separate timeout for the SMU since this will increase the timeout for lots of things, unless we need an overall timeout increase for mode1 reset.

Increase the waiting time to 1s from 200ms. This is expected
to fix some mode1 reset failures.
