[PATCH net-next 1/2] net: dsa: b53: Do not force tagging on CPU port VLANs

Commit ca8931948344 ("net: dsa: b53: Keep CPU port as tagged in all
VLANs") forced the CPU port to be always tagged in any VLAN membership.
This was necessary back then because we did not support Broadcom tags
for all configurations so the only way to differentiate tagged and
untagged traffic while DSA_TAG_PROTO_NONE was used was to force the CPU
port into being always tagged.

This is not necessary anymore since 8fab459e69ab ("net: dsa: b53: Enable
Broadcom tags for 531x5/539x families") and we can simply program what
we are being told now, regardless of the port being CPU or user-facing.
