Ethernet switch on AP148 is connected through MDIO using GPIO 0 and 1.
We'll add the new node using the bitbang driver on these two pins.

This change adds GMAC nodes to IPQ806x platforms, both to the dtsi and
to the AP148 dts. This will provide ethernet connectivity to the device.

This node should be at the root level, not inside the soc node.
