[PATCH v3 6/6] arm64: dts: qcom: qcs6490-rubikpi3: Add audio support

[Hongyang Zhao <hongyang.zhao@thundersoft.com>]

RubikPi 3 uses the AudioReach firmware path for its external audio
interfaces. Primary MI2S connects to an ES8316 codec for headset playback
and capture, while quaternary MI2S feeds the LT9611 HDMI bridge.

Describe the ES8316 supplies, MCLK, jack detection and audio routing, and
add the primary and quaternary MI2S links. The 1.8 V and 3.3 V codec
supplies are both controlled by GPIO117.
