qcacld-3.0: Register dummy APIs to NAN ops

Browse Source 
Kernel needs the below to create NAN interface from driver,
1. Register APIs to the NAN ops. Define dummy APIs as the APIs
   are not supported for the current driver design.
2. Define NAN supported bands and 2GHZ is mandatory.
3. Set the iftype NL80211_IFTYPE_NAN in the supported
   interface_modes.
