Add code to do stream ID switching at the beginning of a job. The stream ID is switched to the stream ID specified by the context passed in the job structure. Before switching the stream ID, an OP_DONE wait is done on the channel's engine to ensure that there is no residual ongoing work that might do DMA using the new stream ID.
