Add StarFive JH8100 dwmac support.
The JH8100 dwmac shares the same driver code as the JH7110 dwmac
and has only one reset signal.
Please refer to below:
JH8100: reset-names = "stmmaceth";
JH7110: reset-names = "stmmaceth", "ahb";
JH7100: reset-names = "ahb";
Example usage of JH8100 in the device tree:
gmac0: ethernet@16030000 {
compatible = "starfive,jh8100-dwmac",
"starfive,jh7110-dwmac",
"snps,dwmac-5.20";
...
};
