[U-Boot] [PATCH] arm64: dts: allwinner: h5: NanoPi NEO Plus2 : add EMAC support

[Antony Antony]

Hi Jonathan,

I got an error with the patch.
arch/arm/dts/sun50i-h5-nanopi-neo-plus2.dtb: ERROR (phandle_references): Reference to non-existent node or label "reg_gmac_3v3"

the attached patch, with reg_gmac_3v3, works for me.
