[PATCH] arm64: dts: rockchip: fix rk3399-puma gmac reset gpio

[Heiko Stuebner]

From: Heiko Stuebner <heiko.stuebner@theobroma-systems.com>

The puma gmac node currently uses opposite active-values for the
gmac phy reset pin. The gpio-declaration uses active-high while the
separate snps,reset-active-low property marks the pin as active low.

While on the kernel side this works ok, other DT users may get
confused - as seen with uboot right now.

So bring this in line and make both properties match, similar to the
other Rockchip board.
