add support for Renesas RZ/N1 ethernet subsystem devices

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.
