cfg80211: add start / stop NAN commands
This allows user space to start/stop NAN interface.
A NAN interface is like P2P device in a few aspects: it
doesn't have a netdev associated to it.
Add the new interface type and prevent operations that
can't be executed on NAN interface like scan.
Define several attributes that may be configured by user space
when starting NAN functionality (master preference and dual
band operation)
