Add support for the EVB1 analog audio to its devicetree. Only the headphone has been tested, since I don't have matching peripherals to test headset or speakers. I also didn't manage to record sound from the onboard microphone, but that also fails with the vendor kernel. Thus I assume the microphone on my board is fried.
