Improve ports handling in e6000sw driver

- recognize ports and vlangroups based on DTS file
- support multi-chip addresing mode (required in upcoming
  Armada-388-Clearfog support)
- refactor attachment function

Each port in 'dsa' node should have 'vlangroup' property. Otherwise,
e6000sw will fail to attach.
