	Instead of harcoding that a core must always be called "DSPn" add a name member to struct wm_adsp so that the owning codec driver can provide a custom name. This allows for re-use of the wm_adsp driver with parts where the processing cores are named differently. If no name is provided the default DSPn name is used.
