wl18xx: use long intervals in sched scan
Add support for long intervals on sched scan. If configured, the original request interval will be used num_short_interval times, and then the long interval will be used. While on it, fix the scan command field names to reflect the expected value is in ms (rather than secs). These values will be taken from the conf file, so bump its version accordingly.
