[PATCH] ARM: dts: sun8i-h3: orange-pi-2: Enable audio codec

[codekipper-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org]

From: Marcus Cooper <codekipper-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>

The Orange Pi 2 routes the LINEOUT pins through a SGM8900 PA which
needs to be enabled. The onboard microphone is routed to MIC1, with
MBIAS providing power.
