ipq806x: ap3935: disable hibernation on LAN1

The Extreme Networks AP3935's LAN1 port (gmac0/RGMII to AR8035 at MDIO
addr 1) fails to acquire a link if no Ethernet cable is connected at
power-on; the port stays dead even after a cable is later inserted, and
only a network restart recovers it.

The AR803x family enables hibernation mode by default, this setting
overrides it.
