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.
