net: stmmac: dwmac-renesas-gbeth: Add support for RZ/G3L SoC

Compared to other Renesas GBETH stmmac glue drivers, RZ/G3L GBETH IP use
the version Synopsys DesignWare MAC (version 5.30). It has an extra clock
compared to RZ/V2H and has ptp_pps_o interrupts. Add support for RZ/G3L
GBETH by reusing device data of RZ/V2H and can be extended to add other
functionalities later.
