realtek: rtl931x: Fix traffic on upper ports

Browse Source 
* traffic isolation tables are different between rtl930x and rtl931x
* traffic_enable/disable/get/set functions span multiple columns in the
  rtl931x as a result, previous implementation would only enable traffic
  in some ports.

traffic_enable/disable and traffic_set/get should now work on all ports and
not just the initial 32
