P2P: Process preferred frequency list as part of GO Neg Req/Resp
When processing a GO Negotiation Request and Response, if local driver
supports the preferred channel list extension, then:
- Check if peer's preference for operating channel is already included
in our preferred channel list and if so, take the oper_channel as is.
- If peer's preference for operating channel is not in local device's
preferred channel list and peer device has provided its preferred
frequency list in the GO Negotiation Request/Response, then find a
channel that is common for both preferred channel lists and use it
for oper_channel.
- If peer's preference for operating channel is not in local device's
preferred channel list and peer device doesn't use preferred channel
list extension, i.e., no preferred channel list in GO Negotiation
Request/Response, then look for a channel that is common for local
device's preferred channel list and peer's list of supported channels
and use it for oper_channel.
- In case no common channel is found, use the peer's preference for
oper_channel as is.
