xilinx_axidma: Do not set DMA .notify to NULL after notify

If a stream notify function is not ready, it may re-populate the notify call-
back to indicate it should be re-polled later. This break in this usage, as
immediately following the notify() call, .notify is set to NULL. reverse the...

qdev: Drop taddr properties

Drop all the infrastructure for taddr properties (ie ones which
are 'hwaddr' sized). These are now unused, and any further desired
use would be rather questionable since device properties shouldn't
generally depend on a type that is conceptually variable based on...

Remove unneeded type casts

cpu_physical_memory_read, cpu_physical_memory_write take any pointer
as 2nd argument without needing a type cast.

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: 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...
