arm64: dts: mediatek: mt8395-nio-12l: Enable Audio DSP and sound card 



Add memory regions for the Audio DSP (ADSP) and Audio Front-End (AFE),
and enable both components in the device tree.

Also, define the required pin configuration and add a sound card node
configured to use the ADSP. This enables audio output through the 3.5mm
headphone jack available on the board.
