rtl83xx: dsa: disable VLAN filtering on CPU port

Browse Source 
Before driver code
 - enabled egress filter for cpu and non-cpu ports
 - enabled ingress filter for non-cpu ports

This patch explicitly enables ingress and egress filtering for non-cpu
ports and disables ingress and egress filtering for cpu port.
