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.

The DMACTX field determines which context, as specified in the TRANSCFG register, is used. While during boot it doesn't matter which is used, later on it matters and this value is reused by the firmware.

For engines that support context isolation, allocate a context when opening a channel, and set up stream ID offset and context fields when submitting a job.

As of this commit, the stream ID offset and fallback stream ID are not used when context isolation is disabled. However, with upcoming patches that enable a full featured job opcode sequence, these will be necessary.
