ASoC: core: Add support for machine specific trigger callback
Machine specific trigger callback allows to do final stream start/stop related operations in a machine driver after setting up the codec, DMA and DAI. One example could be clock management for linked streams case where machine driver can start/stop synchronously the linked streams.
