Currently ini variable gWlanMccToSccSwitchMode has 4 values.
Value 3 enforces SCC in anycase, if SCC is not possible then switchoff
the AP.
Added new value 5 for auto specific scenarios where, if SCC is not
possible the allow MCC.

Updated PCL table to support 3-port concurrent scenarios AP+AP+STA,
AP+GO+STA and AP+AP+AP.
The PCL entries are updated to have below behavior:
1. AP+GO or AP+AP will be supported either in DBS or in SCC mode
2. The Precedence order will be DBS, SCC.
Also disabling 3-port combinations with P2P-CLI.

There are many QDF APIs require a qdf_handle_t parameter. None of these
APIs actually use the qdf_handle_t parameter, meaning it can be
completely removed. As a step toward globally removing this unused
type, remove qdf_handle_t parameters from unsed qdf_defer APIs.

Refactor the code to dynamically change the conc_system_pref.
Whenever user changes conc_system_pref from application,
driver is overwriting the conc_system_pref which is getting
populated from ini file. Once it is overwritten there is no way
to get the configured value for this setting. So add a new
variable to hold the value of conc_system_pref without disturbing
default value read from ini file.

When softap is stopping, there are two threads
accessing the "conc_connection_list".
hostapd thread (__wlan_hdd_cfg80211_stop_ap) read

cds_mc_thread thread (cds_get_valid_chan_weights)
read and modify it by cds_store_and_del_conn_info

They are not protected,which causes two same

This fix is to acquire lock before read/modify

In case of STA-AP case, new thread is created to call the func
policy_mgr_check_sta_ap_concurrent_ch_intf() that calls
policy_mgr_get_pcl_for_existing_conn() that modifies
pm_conc_connection_list table. The mc_thread calls
policy_mgr_get_valid_chan_weights() that also modifies
pm_conc_connection_list table. But the race condition is
created that mess up the pm_conc_connection_list table.
This race condition also leads to the scenario where the STA
connection to the AP is not updated properly . This shall lead
to the improper PCL update for a STA+SAP concurrency and thus
the channel switch fails.
The fix is to protect the whole sequence of the function
policy_mgr_check_sta_ap_concurrent_ch_intf() with mutex to avoid
race condition.
