[PATCH v2 2/2] ASoC: dt-bindings: google,sc7280-herobrine: Add platform property

[Srinivasa Rao Mandadapu <quic_srivasam@xxxxxxxxxxx>]

Add platform property in sc7280 machine driver bindings for including
platform subnode in dai-links.
This is required for binding the frontend dai driver with codec driver
and cpu driver and to do dynamic pcm routing in ADSP based platforms.
