net: pcs: rzn1-miic: update speed only if interface is changed

As stated by Russel King, miic_config() can be called as a result of
ethtool setting the configuration while the link is already up. Since
the speed is also set in this function, it could potentially modify
the current speed that is set. This will only happen if there is
no PHY present and we aren't using fixed-link mode.

Handle that by storing the current interface mode in the miic_port
structure and update the speed only if the interface mode is going to
be changed.

Merge branch 'Renesas-rz-n1'

Clément Léger says:

====================
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.

net: pcs: add Renesas MII converter driver

Add a PCS driver for the MII converter that is present on the Renesas
RZ/N1 SoC. This MII converter is reponsible for converting MII to
RMII/RGMII or act as a MII pass-trough. Exposing it as a PCS allows to
reuse it in both the switch driver and the stmmac driver. Currently,
this driver only allows the PCS to be used by the dual Cortex-A7
subsystem since the register locking system is not used.
