From: Biju Das <biju.das.jz at bp.renesas.com>

The Renesas RZ/G3L GBETH IP uses Synopsys DesignWare MAC version 5.30
compared to other Renesas SoC such as RZ/V2H that use MAC version 5.20.

The RZ/G3L GBETH requires an extra clock compared to RZ/G3E and has pps
interrupts. Document the Renesas RZ/G3L GBETH IP in bindings and enable
the Gigabit Ethernet Interface (GBETH0) populated on the RZ/G3L SMARC
EVK. The eth1, pincontrol definitions and hotplug support will be added
later.
