net: dsa: lantiq_gswip: treat VID 0 like the PVID

Browse Source 
Documentation/networking/switchdev.rst says that VLAN-aware bridges must
treat packets tagged with VID 0 the same as untagged. It appears from
the documentation that setting the GSWIP_PCE_VCTRL_VID0 flag (which this
driver already had defined) might achieve this.
