ARM: dts: allwinner: orangepi-zero-plus2: Add default audio routing
The Orange Pi Zero Plus 2 has the same pinout[1] as the Orange Pi
Zero[2] (with the possible exception of line-out left/right being
swapped), and the Orange Pi Zero Interface Board is sold[3] as
compatible with both of them. We can thus use the same audio routing.
