arm64: dts: rockchip: pull down rst-gpio of gmac-phy at suspend for rk3399-box
Some phys would not enter low power mode by writing 'power down'
bit into phy common register0 such as RTL8211E. And pulling down
reset gpio is also a common way to make phy get low consumption,
if the supplied regulator of phy could not be disabled at suspend.
