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.
