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",
		"top_clk26m_clk";

Example:

	afe: mt8183-afe-pcm@11220000  {
		compatible = "mediatek,mt8183-audio";
		reg = <0 0x11220000 0 0x1000>;
		interrupts = <GIC_SPI 161 IRQ_TYPE_LEVEL_LOW>;
		resets = <&watchdog MT8183_TOPRGU_AUDIO_SW_RST>;
		reset-names = "audiosys";
		power-domains = <&scpsys MT8183_POWER_DOMAIN_AUDIO>;
		clocks = <&infrasys CLK_INFRA_AUDIO>,
			 <&infrasys CLK_INFRA_AUDIO_26M_BCLK>,
			 <&topckgen CLK_TOP_MUX_AUDIO>,
			 <&topckgen CLK_TOP_MUX_AUD_INTBUS>,
