Set Wi-Fi Configuration attribute to restrict offchannel operations

Browse source 
This commit defines an attribute to
QCA_NL80211_VENDOR_SUBCMD_SET_WIFI_CONFIGURATION -
QCA_WLAN_VENDOR_ATTR_CONFIG_RESTRICT_OFFCHANNEL which can be used to
restrict offchannel operations on the AP/GO interface.

The goal is to restrict any operations which would cause the AP/GO to
leave its operating channel.

* This will restrict the scans to the AP/GO operating channel and the
* channels of the other band, if DBS is supported.A STA/CLI interface
* brought up after this setting is enabled, will be restricted to
* connecting to devices only on the AP/GO interface's operating channel
* or on the other band in DBS case. P2P supported channel list is
* modified, to only include AP interface's operating-channel and the
* channels of the other band if DBS is supported.
*
* These restrictions are only applicable as long as the AP/GO interface
* is alive. If the AP/GO interface is brought down then this
* setting/restriction is forgotten.
*
* If this variable is set on an AP/GO interface while a multi-channel
* concurrent session is active, it has no effect on the operation of
* the current interfaces, other than restricting the scan to the AP/GO
* operating channel and the other band channels if DBS is supported.
* However, if the STA is brought down and restarted then the new STA
* connection will either be formed on the AP/GO channel or on the
* other band in a DBS case. This is because of the scan being
* restricted on these channels as mentioned above.
*
* 1-Disable offchannel operations, 0-Enable offchannel operations.
