ipq806x: ubnt,unifi-ac-hd: use on-board PHYs

Unlike many ipq806x devices, Ubiquiti UniFi AC HD (UAP-AC-HD, UAP301)
has no switch on board. Its two Ethernet ports are connected to Atheros
AR8033 PHYs. It is not appropriate to use fixed-link in this
configuration. Instead, configure the correct PHYs in the device tree
configuration to allow the at803x driver to load.
