rtlwifi: btcoex: 21a 2ant: add multiport action for p2p/miracast

For p2p/miracast, the wifi may have multiple ports for different roles.
Under this, we need extra settings for turning off the tdma and proper
coex table parameters.

We monnitor the number of links on a port to determine if it is for
p2p/miracast or not.
