Subject: [PATCH] net: stmmac: fix the mistake of the device tree property string of reset gpio in stmmac_mdio_reset

From: "zhili.liu" <zhili.liu@...s.com.cn>

According to Documentation/devicetree/bindings/net/snps,dwmac.yaml,
the device tree property of PHY Reset GPIO should be "snps,reset-gpio".

Use string "snps,reset-gpio" instead of "snps,reset" in stmmac_mdio_reset
when invoking devm_gpiod_get_optional.

Fixes: 7c86f20d15b7 ("net: stmmac: use GPIO descriptors in stmmac_mdio_reset")
