net: dsa: sja1105: add static tables for virtual links

This patch adds the register definitions for the:
- VL Lookup Table
- VL Policing Table
- VL Forwarding Table
- VL Forwarding Parameters Table

These are needed in order to perform TTEthernet operations: QoS
classification, flow-based policing and/or frame redirecting with the
switch.
