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";
