arm64: dts: mediatek: asurada: Enable audio support

Enable audio support for the Asurada platform. This consists of the
machine sound card, the rt1015p codec for the speakers, the rt5682 codec
for the headset, and the dmic codec for the internal microphone.

Newer revisions of spherion and hayato use the rt5682s codec for the
headset instead, so the codecs and card compatible are added through
separate dtsi files to prepare for that.

HDMI audio support is left out for now since the DisplayPort chip
required isn't enabled yet.
