[PATCH net-next] net: dsa: b53: Add debug prints in b53_vlan_enable()

[Florian Fainelli]

Having dynamic debug prints in b53_vlan_enable() has been helpful to
uncover a recent but update the function to indicate the port being
configured (or -1 for initial setup) and include the global VLAN enabled
and VLAN filtering enable status.
