ah, in Amlogic's kernel the directories are probably

this looks good to me. so you have tried:
gpio = <&gpio GPIOZ_1 GPIO_ACTIVE_HIGH>;

as well as:
gpio = <&gpio GPIOZ_1 GPIO_ACTIVE_LOW>;
// enable-active-high; not set

you already have phy-mode = "rgmii"; in your .dts so this looks fine.
maybe the pinctrl driver is missing some bits for rgmii mode, can you
please run "md 0xc11080b0 0x28" in u-boot and paste the output (this
dumps the pinctrl mux mode registers from u-boot, where I assume that
ethernet is working)?
do you see any dwmac/stmmac related errors in your kernel log?
