Look at the active low DT property of a GPIO.since the phylib code can't satisfy resetting PHY in IPQ chipset, phylib
resets phy by
configuring GPIO output value to 1, then to 0. however the PHY reset in
IPQ chipset need
to configuring GPIO output value to 0, then to 1 for the PHY reset, so i
put the phy-reset-gpios here.

thanks Andrew, will update it in the next patch set.
