qcacld-3.0: Add INI parameter to configure NAN in 6GHz

Currently, there is no INI parameter to control NAN feature in 6GHz
frequency band. Because of this, there is no provision to disable the
NAN in 6GHz when there is no requirement.

To address this, add INI parameter to configure NAN feature in 6GHz.
