ARM: dts: allwinner: Add Orange Pi Zero Interface Board overlay

Browse Source 
The Orange Pi Zero interface board is a (mostly) passive adapter from the
13-pin header of the Orange Pi Zero and Orange Pi Zero Plus2 to standard
connectors (2x USB A, 1x Audio/Video output, 1x built-in microphone, 1x
infrared input). Headphones, microphone, infrared (CIR) input, and USB
have been tested with the Orange Pi Zero.

CVBS output is currently not supported.
