[PATCH 1/2] Documentation: dsa: b53: fix stale tagging-support section

[Christian Melendez]

5325/5365 were listed under "Configuration without tagging support".
b53_get_tag_protocol() assigns them DSA_TAG_PROTO_BRCM_LEGACY_FCS
(commit c3cf059a4d41), implemented in net/dsa/tag_brcm.c. Move them to
the tagging-supported section.

539x/531x5, the only chips left in that section, get no special case
in b53_get_tag_protocol() either. The section and its config examples
no longer apply to any b53 switch, so remove them.

-Configuration without tagging support
--------------------------------------
-
-Older models (5325, 5365) support a different tag format that is not supported
-yet. 539x and 531x5 require managed mode and some special handling, which is
-also not yet supported. The tagging support is disabled in these cases and the
-switch need a different configuration.
-
-The configuration slightly differ from the :ref:`dsa-vlan-configuration`.
-
-The b53 tags the CPU port in all VLANs, since otherwise any PVID untagged
-VLAN programming would basically change the CPU port's default PVID and make
-it untagged, undesirable.
-
-In difference to the configuration described in :ref:`dsa-vlan-configuration`
-the default VLAN 1 has to be removed from the user interface configuration in
-single port and gateway configuration, while there is no need to add an extra
-VLAN configuration in the bridge showcase.
