====================
net: dsa: hellcreek: Add support for dumping tables

add support for dumping the VLAN and FDB table via devlink. As the driver uses
internal VLANs and static FDB entries, this is a useful debugging feature.

Changes since v1:

 * Drop memory reporting as there are better APIs to expose this
 * Move comment to VLAN patch

Previous versions:
