ARM: dts: sun5i: q8-common: Enable audio codec
The Q8 tablets use the audio codec to provide audio output via a headphone jack or a small mono speaker. A GPIO output is used to control speaker amp. The tablets may or may not have an internal microphone. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>
