In case of STA+SAP, if STA connect to new channel, driver check
if SAP channel switch is required. Before this it wait if channel
switch is already in progress, if not it continue and check if
channel change is required. While waiting in case where event was
set and channel switch was not in progress, the even gets reset
after waiting.
So if event is not set again, i.e in case SAP channel change is not
required. Any subsequent wait on the event will result in timeout.
Also while changing channel this event is reset and then the
concurrency checks are made and if checks fails the channel change
may not happen leaving event in reset state.
So wait for event only if channel switch is already in progress.
Also reset the event once all concurrency checks have passed and
channel change is started.

In 2x2 DBS mode once STA/SAP change channel from 2.4Ghz to 5Ghz,
policy_mgr_get_current_pref_hw_mode_ptr never return
PM_SINGLE_MAC_UPGRADE to start the opportunistic timer to switch to
single mac mode.
Fix is to check and start opportunistic timer once connection info are
updated. Also start opportunistic timer before
check for SAP to change channel as when SAP change channel it should
stop opportunistic timer and set required HW mode.
If single mac mode is required after channel switch it will start
opportunistic timer again in channel switch callback.

If DBS 2x2 mode is supported, to operate in 2.4Ghz the driver needs to
be in DBS mode before vdev start/restart is sent on 2.4Ghz channel.
If STA is connected to a 5Ghz channel and the PEER AP switch from 5Ghz
to 2.4Ghz channel, it sends vdev restart without sending the HW mode
change to firmware.
Fix is to set HW mode before the initiating vdev restart if new channel
is 2.4Ghz and 2x2 DBS is supported and current HW mode is not DBS

Current ACS logic sometimes selects MCC channel based on its
algo for SAP / GO which results in SAP / GO bring-up failures.
This issue is seen in below concurrency combinations:
1. SAP + SAP
2. SAP + P2P-GO
3. SAP + SAP + SAP
4. SAP + SAP + P2P-GO
So with this change driver restricts ACS scan to intersection of
PCL and ACS channel list.
This implementation will take care of existing STA + SAP case as well,
as PCL will have channels according to 1st connection being STA.

If DBS 2x2 mode is supported, to operate in 2.4Ghz the driver needs to
be in DBS mode before vdev start/restart is sent on 2.4Ghz channel.
In scenareo with gWlanMccToSccSwitchMode 4, when AP is in 5Ghz and
STA connect to any other channel in 5ghz, it force AP to switch to 2.4 Ghz
channel. Thus AP sends vdev restart without sending the HW mode change
to firmware.
Fix is to set HW mode before the AP start channel switch.

In function policy_mgr_is_restart_sap_allowed, STA+SAP concurrency is
decided based on return status of policy_mgr_get_concurrency_mode.
It can happen, SAP adapter is opened. But hostapd_open and start_ap
is not done. Then, this api will return SAP bit true even even though
SAP is not active. So, explicitly check if the SAP is active by
checking the SAP connection count along with the concurrency mode.
This can result in GO channel override with STA channel.
Hence check the sap and go mode connection count along
with the concurrency mode.

If DBS is disabled from INI then driver just bails out
in wlan_hdd_update_dbs_scan_and_fw_mode_config() API and never report
it to FW. This creates a confusion when DBS is disable INI but our HW
is capable of doing DBS, i.e. driver thinks that DBS disabled
but FW thinks that DBS is enabled.
Provide a fix that driver should report exact INI setting to FW.
This issue got introduced as part of regression caused by:
Iec2ef7e77e91f332028904c319d24e1ed134306d
ROME platform doesn't support any DBS related commands in FW,
so if driver sends wmi command with dual_mac_config with all params
set to 0 then FW wouldn't respond back and driver would timeout on
waiting for response. This was the original issue for which
Iec2ef7e77e91f332028904c319d24e1ed134306d was added.
Make sure current solution doesn't break backward compatibility.
Add a check to make sure FW supports DBS to eliminate
ROME vs NON-ROME platform.
