[net-next v2 2/5] dt-bindings: net: starfive,jh7110-dwmac: Add JHB100 support

[Minda Chen]

Add StarFive JHB100 dwmac support and compatible.
The JHB100 dwmac shares the same driver code as the JH7110 dwmac,
which contains 2 SGMII interfaces, 1 RGMII/RMII interface and
1 RMII interface.
JHB100 dwmac has only one reset signal and one main interrupt
line.

Please refer to below:

JHB100: reset-names = "stmmaceth";

Example usage of JHB100 in the device tree:

gmac0: ethernet@11b80000 {
        compatible = "starfive,jhb100-dwmac",
                     "snps,dwmac-5.20";
        interrupts = <225>;
        interrupt-names = "macirq";
        ...
};
