cnss2: Update time sync period based on tsf sync start/stop

Browse Source 
Add cnss_update_time_sync_period and cnss_reset_time_sync_period to
update time sync period vote sent from wlan driver based on use-case.
CNSS driver stores both wlan driver and sys config time sync period
value and will apply the minimum value of all votes.
