[PATCH 1/9] dt-bindings: sound: mt2701-afe-pcm: add HDMI audio path clocks

[Daniel Golle]

Document four additional optional clocks feeding the HDMI audio
output path on MT2701 and MT7623N: the HADDS2 PLL (root of the
HDMI audio clock tree), the HDMI audio and S/PDIF interface power
gates, and the audio APLL root gate. Older device trees that do
not wire these up remain valid via minItems.
