arm64: dts: mediatek: mt8395-genio-1200-evk: Enable Audio DSP and sound card

Add in the mt8395-genio-1200-evk devicetree the memory regions for the
Audio DSP (ADSP) and Audio Front-End (AFE), and a sound card node
configured to use the ADSP.
This enables audio output through the 3.5mm headphone jacks (speaker or
earphone), available on the board.
