habanalabs: increase h/w timer when checking idle
In GAUDI the current timer value for the hardware to check if it is in IDLE state is too low. As a result, there are occasions where the H/W wrongly reports it is not IDLE. The driver checks that before submitting work on behalf of the driver during initialization, so a false report might cause the driver to fail during device initialization.
