The ethernet phy of rk3066a-rayeager has a reset pin, it controlled by
GPIO1_D6, this pin should be pull down then pull up to reset the phy.
Add a reset-gpios property in phy0, make the phy can be reset when emac
power on.

looks like the phylib-patches were accepted some days ago,
so I've now also applied this patch for 4.16, after fixing the subject
by adding the "rockchip:" to "ARM: dts: rockchip": :-)
