[PATCHv1 linux-next 1/4] dt-bindings: net: rockchip-dwmac: fix rv1126 compatible warning

[Anand Moon]

Fix compatible string for RV1126 gmac, and constrain it to
be compatible with Synopsys dwmac 4.20a.

fix below warning
arch/arm/boot/dts/rv1126-edgeble-neu2-io.dtb: ethernet@ffc40000:
		 compatible: 'oneOf' conditional failed, one must be fixed:
        ['rockchip,rv1126-gmac', 'snps,dwmac-4.20a'] is too long
        'rockchip,rv1126-gmac' is not one of ['rockchip,rk3568-gmac', 'rockchip,rk3588-gmac']
