The GPIO0 is an output mode, and output data high at default is to power
down internal PHY and other external MII device
GP1~3 defaults are input ports, GP 0, 4~6 force to output ports.

This pin is also used as a strap pin to define whether the MII interface is a
reversed MII interface (pulled high) or a normal MII interface (not pulled
high). This pin has a pulled down resistor about 60k ohm internally.
O,PD Issue a wake up signal when wake up event happens
This pin has a pulled down resistor about 60k ohm internally.
