Merge #209

209: Allow for skipping an ongoing DMA transfer if not using double buffering r=therealprof a=thalesfragoso

This also fixes a problem that could happen when disabling the stream with an active transfer. The code is also updated to use the `embedded-dma` crate now.

As draft because I didn't test it on hardware yet.
