Previously topology kernel driver assumes a widget can have only one emumerated mixer control. We need to remove this restriction for Broxton. Its firmware modules (widgets) may need multiple enum controls based on the channel and MIC combination. No ABI change is needed. The ABI allows a widget to embed multiple controls.
