kc705: simplify DRTIO master & satellite 

* KC705 master: user can no longer choose whether or not the SMA acts as the 2nd DRTIO channel; SFP and SMA now act as the 1st and 2nd channel respectively by default.
* KC705 satellite: user should now use `--sma` to enable using the SMA as the satellite channel; SFP acts as the satellite channel by default.
