From: Biju Das <biju.das.jz@bp.renesas.com>
Add device tree binding support for the Gigabit Ethernet (GBETH) IP on
Renesas RZ/G3L SoC. This SoC uses different Synopsys DesignWare MAC
version 5.30 compared to RZ/G3E.
RZ/G3L requires an extra clock compared to RZ/G3E and has pps interrupts.
Add a new compatible string "renesas,r9a08g046-gbeth" for RZ/G3L SoC and
update the schema to handle hardware differences between SoC variants.
Extend the base snps,dwmac.yaml schema to accommodate the PPS interrupts.

v2->v3:
* Fixed the typo ppt->ptp as pointed by netdev-ai[1].
* Keep the tag as the change is trivial
