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...

xilinx_axienet/dma: Implement rx path flow control

Implement flow control for the RX data path from xilinx_axienet->xilinx_axidma.
On short return from axidma, then ethernet sets up the notify callback to resume
transfer from where it left off.

This also allows the ethernet to track whether there is an in progress transaction...

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.

xilinx_axidma: typedef XilinxAXIDMA struct

Typedef xilinx_axidma's object state struct to shorten the repeated usages of
struct XilinxAXIDMA.

xilinx_axidma: Register reset properly

xilinx_axidma: converted init->realize

The prescribed transition from SysBusDevice::init to Device::realize. I'm going
with Andreas suggestion to move the sysbus foo to Object::init for early IRQ
visibility.

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...
