qcacmn: Add ucfg API to reset im stats and freq ctrl params

Browse source 
When dcs happened for three times in five minutes, then do
restart(start/stop) SAP operation, when SAP is started again,
dcs may happen again quickly, if total four times dcs happened
in five minutes, dcs_disable_timer will be started due to dcs
happened frequency control policy, it will disable wlan
interference detection for 30 minutes and dcs interference
detection won't work for 30 minutes, it's unreasonable. After
SAP restart, dcs happened times should be calculated from zero.

Add ucfg API to reset im stats and freq ctrl params.
