ASoC: mediatek: mt2701: add optional HDMI audio path clocks

Browse source

The HDMI audio output path on MT2701/MT7623N is rooted in HADDS2PLL
and gated by the audio_hdmi, audio_spdf and audio_apll power gates.
Acquire these four clocks from device tree using devm_clk_get_optional
so that existing platforms which do not wire up HDMI audio keep
probing unchanged. Actual clock enable/prepare is deferred to the
upcoming HDMI DAI startup path.
