[PATCH] ARM: dts: sun8i: Fix power for USB Ethernet controller

[Hauke Mehrtens]

The RTL8152B USB controller needs a 3.3 volt power supply which is
controlled by PAD20. Without this patch Linux will not see that there is
a device connected to the USB bus and the 2. USB port will not work.

I do not of a better solution to add a regulator to a USB device.
