Subject: [PATCH 4/9] ASoc: dt-binding: Convert mt8183-afe-pcm binding to
YAML
Convert the MediaTek MT8183 AFE PCM Device Tree binding from the old
.txt format to YAML schema format to improve validation.
While converting, also document all clock inputs used by the AFE block.

-Mediatek AFE PCM controller for mt8183
-
-Required properties:
-- compatible = "mediatek,mt68183-audio";
-- reg: register location and size
-- interrupts: should contain AFE interrupt
-- resets: Must contain an entry for each entry in reset-names
- See ../reset/reset.txt for details.
-- reset-names: should have these reset names:
- "audiosys";
-- power-domains: should define the power domain
-- clocks: Must contain an entry for each entry in clock-names
-- clock-names: should have these clock names:
- "infra_sys_audio_clk",
- "mtkaif_26m_clk",
- "top_mux_audio",
- "top_mux_aud_intbus",
- "top_sys_pll3_d4",
