accel/habanalabs: extend preboot timeout when preboot might take longer
There are cases such when FW runs MBIST, that preboot is expected to take
longer than the usual. In such cases the firmware reports status
SECURITY_READY/IN_PREBOOT and we extend the timeout waiting for it.
This is currently implemented for Gaudi2 only.
