cfg80211: fix NAN bands definition
The nl80211_nan_dual_band_conf enumeration doesn't make much sense. The default value is assigned to a bit, which makes it weird if the default bit and other bits are set at the same time. To improve this, get rid of NL80211_NAN_BAND_DEFAULT and add a wiphy configuration to let the drivers define which bands are supported. This is exposed to the userspace, which then can make a decision on which band(s) to use. Additionally, rename all "dual_band" elements to "bands", to make things clearer.
