Since any channel can be assigned to a vif being brought up, the vdev cannot be created during add_interface(). Hence defer the vdev creation till channel assignment. If only one radio is part of the wiphy, then the existing logic is maintained, i.e vdevs are created during add interface and started during channel assignment. This ensures no functional changes to single pdev devices which has only one radio in the SoC.

Hence, When antenna set/get is received we adjust the set/get based on max radio capability and set/get antenna accordingly. Multi radio capability needs to introduced with interface combination changes to support single wiphy model in cfg80211 which would help extend the wiphy specific get/set configs similar to this to per hw level.

Use the idx to identify the appropriate sband since multiple bands could be combined for single wiphy case. Also use the channel idx and sband to identify the corresponding radio on which the survey results needs to be populated.
