net: dsa: modularize DSA_TAG_PROTO_NONE

There is no reason that I can see why the no-op tagging protocol should
be registered manually, so make it a module and make all drivers which
have any sort of reference to DSA_TAG_PROTO_NONE select it.

Note that I don't know if ksz_get_tag_protocol() really needs this,
or if it's just the logic which is poorly written. All switches seem to
have their own tagging protocol, and DSA_TAG_PROTO_NONE is just a
fallback that never gets used.

====================
net: dsa: microchip: DSA Driver support for LAN937x

LAN937x is a Multi-Port 100BASE-T1 Ethernet Physical Layer switch
compliant with the IEEE 802.3bw-2015 specification. The device provides
100 Mbit/s transmit and receive capability over a single Unshielded
Twisted Pair (UTP) cable. LAN937x is successive revision of KSZ series
switch.
This series of patches provide the DSA driver support for
Microchip LAN937X switch through MII/RMII interface. The RGMII interface

Merge branch 'Renesas-rz-n1'

====================
net: add support for Renesas RZ/N1 ethernet su

The Renesas RZ/N1 SoCs features an ethernet subsystem which contains
(most notably) a switch, two GMACs, and a MII converter [1]. This
series adds support for the switch and the MII converter.

The MII converter present on this SoC has been represented as a PCS
which sit between the MACs and the PHY. This PCS driver is probed from
the device-tree since it requires to be configured. Indeed the MII
converter also contains the registers that are handling the muxing of
ports (Switch, MAC, HSR, RTOS, etc) internally to the SoC.

The switch driver is based on DSA and exposes 4 ports + 1 CPU
management port. It include basic bridging support as well as FDB and
statistics support.
