[PATCH] drm/audio: declaration of struct device

[Ramalingam C]

Header has used the references to struct device without it definition
or declaration. Hence resulting in compilation warning such as

  "'struct device' declared inside parameter list..."

This changes adds a declaration to struct device in the header to avoid
any such warnings.
