ASoC: dt-bindings: mediatek,mt8188-mt6359: Add mediatek,adsp property
On some MediaTek SoCs, an Audio DSP (ADSP) is integrated as a separate
hardware block that leverages Sound Open Firmware (SOF) and provides
additional audio functionalities. This hardware is optional, and the
audio subsystem will still function normally when it's not present.
To enable ADSP support, a 'mediatek,adsp' property is required in the
sound card node to pass the ADSP phandle. This allows AFE to link to
ADSP when the sound card is probed.
MT8188 has ADSP integrated, so add the 'mediatek,adsp' property to
allow using it in the audio subsystem.
This fixes dtbs_check error:
Unevaluated properties are not allowed ('mediatek,adsp' was
unexpected)
