qcacmn: Add wifi configuration attribute restrict offchannel
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.

+ * brought up after this setting is enabled, will be restricted to

+ * These restrictions are only applicable as long as the AP/GO interface

+ * 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
