Peter Crosthwaite 42bb9c9178 stream: Remove app argument hack 
The uint32_t *app argument doesn't exist in real hardware. It was a hack in
xilinx_axidma/enet to fake the (secondary) control stream connection. Removed
the argument and added the second stream to axienet/dma.

Peter Crosthwaite 35e60bfdbc stream: Add flow control API 
Add basic flow control to stream. A stream slave may return short, indicating
that it is not capable of accepting any more data at the present time. Polling
or a callback can be used via the can_push() function to determine when the
slave can receive again.
