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.

xilinx_axidma: Create Proxy object for stream
Create a separate child object to proxy the stream slave connection. This is
setup for future work where a second stream slave connection is needed. The
new child object is created at qdev init time and is linked back to the parent
(the ethernet device itself) automatically.
Stream slave masters differentiate which slave connection they are connected to
by linking to the proxy object rather than the parent.

explicitly call it from the sysbus::init.
