When AFC event come and update 6 GHz SP channels' state and power
attribution, SAP which already started on 5 GHz or 6 GHz channel
can move in or out from SP channel, which has higher tx power limit.
SAP target channel/bandwidth is decided by ACS channel select callback
register to SAP module, which will take channel max tx power limit
into account.
After target channel/bandwidth determined, SAPs move to same target
channel/bandwidth with eCSA process. If violate any concurrency
limitation, AFC DCS process should abort.
Add AFC component id and reference id.

The parameters of ucfg_dcs_get_ch_util should be the same whether
DCS_INTERFERENCE_DETECTION is defined or not.

Add API to get channel utilization values from DCS , which can be used by
other components, like EasyMesh.

Handle DCS-AWGN event and take actions accordingly:
For STA mode, if the interference locates on primary 20MHz,
disconnect from AP; otherwise, find a max interference free width
and trigger channel change.
For SAP mode, if the interference locates on primary 20MHz,
try to select a random interference free channel and trigger channel
change (stop SAP if no channel is selected); otherwise, find a max
interference free width and trigger channel change.

interference event received from FW.

Always enable DCS firmware wmi_dcs_interference_event_id event
indication as CCA feature requires, for below scenario, will
ignore dcs event data and won't do interference detection
algorithm calculation:
a: Current SAP channel isn't on 5G band
b: In the process of ACS
c: In the process of dcs disabling dcs_restart_delay time duration

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.
