Add channel tx max power factor to existing ACS channel weight logic,
so if AFC available can automatically select Standard Power channel

DCS module will invoke this callback and dynamic switch to best
channel/bandwidth if possible.

Currently, there is duplicate logic in function
wlansap_roam_process_ch_change_success to invoke
function wlansap_start_beacon_req.
a\ wlansap_roam_process_ch_change_success ->
wlansap_start_beacon_req(sap_ctx)
b\ wlansap_roam_process_ch_change_success ->
sap_fsm -> sap_fsm_state_starting ->
wlansap_start_beacon_req(sap_ctx)
This causes fw crash since it sends vdev up twice.
Also in SAP + SAP scenario, there is a race in updating global
variable mac_ctx->sap.SapDfsInfo.sap_radar_found_status. Move the
variable to sap_ctx per vdev to avoid such race.

To reduce the ACS time, there is an implementation wherein one
user space process creates sap interface and queues ACS request to driver,
meantime framework initializes various config and starts hostapd
to queue same ACS request to driver. In this scenario, there is a
race condition that hostapd tries to queue ACS request while there is
already one ACS request is in progress. With current implementation,
driver will reject second ACS request and return error to hostapd
leading to sap turn on failure.
This change allows subsequent ACS request if all the attributes
of do_acs vendor command matches with the ongoing ACS request and returns
success to userspace. There is no another ACS scan queued as part of
second ACS request which is same as ongoing ACS request because the result
of ongoing ACS request will act as result of second ACS request as well.

Currently, ACS computation triggers when ACS scan complete event is
received after firmware has scanned all channels. This leads to
delay in selection on SAP channel.
As an optimization, this change selects the first clean channel
while scan is still in progress. The criteria for first clean channel
is that no beacon/probe response should be received on that channel.
If such channel is obtained while scan is in progress, then select this
channel as SAP channel and abort ongoing scan. Firmware sends
wma_chan_info_event per channel this change uses this event as an
indication that scan is completed on that channel.
To further increase the optimize the time to get clean channel, sort the
ACS frequency list in descending order in ACS SCAN request to
firmware. Firmware scans the channel in the order given by host
in scan request, as higher band channels are less occupied, the
probability of getting clean channel initially will increase, which
will lead to selecting the channel in less time and thereby reduce
the SAP turn on time.

Previously, if STA is connected to DFS channel and SAP starts on
Non-DBS HW, then it is forced to start on DFS channel with BW 160 Mhz
irrespective of BW on which STA is connected without CAC.
Even after STA disconnects, SAP remains on DFS channel with BW 160Mhz.
So, scan will be disabled and STA cannot be connected on any channel
other than DFS channel.
If STA is connected on non-DFS channel on 5 GHz and SAP starts, it
will start on non-DFS channel as primary channel with BW 160 Mhz
without CAC. Also, scanning was also allowed when SAP is started with
BW 160 Mhz. This might violate regulatory in case radar comes up while
scanning.
Standalone SAP on DFS channel was not allowed.
To fix this, Force set SCC for non-dbs HW, this way standalone SAP
can come on DFS channel but scan will be disabled in such case and
STA cannot be connected other than DFS channel.
In case STA gets connected to dfs channel in non-dbs HW, then sap
starts only on STA channel with force SCC with BW
MIN(sta_chan_width, CH_WIDTH_80MHZ).
Afterwards, if STA disconnects, restart the AP with BW CH_WIDTH_80MHZ
on safe channel. Scan will be allowed as the DFS master capability is
offloaded to AP with which STA is connected on DFS channel.
Also, if standalone sap starts, then STA connects to DFS channel then
SAP will restart with STA channel frequency and Channel width
MIN(sta_chan_width, 80MHZ).
If standalone SAP starts and then STA connects to non-dfs AP or SAP
starts when STA is already connected to non-DFS AP, then ch_width is
MAX(sta_chan_width, 80MHZ) (5 Ghz) or 20 Mhz (2.4 Ghz).
If STA disconnects during SAP+STA on non-DFS, SAP won't restart unless
the STA was connected on BW 160 Mhz.
