Sean Anderson 13ee4899a3 doc: Expand interfaces documentation 
Expand a bit on the AXI stream and Wishbone interfaces, documenting the
particular choices we use. The reset signalling could likely also use
some further documentation, but I have deferred that until I have gone
though all the cores and fixed bugs.

Sean Anderson 12b98c8d46 doc: Move interface documentation to its own document 
This is more detailed technical documentation, and doesn't really need
to go at the top-level.

Sean Anderson 75142311f2 Add AXIS-Wishbone bridge 
This adds the core of the UART-Wishbone bridge. The protocol has
a variable-length address phase to help reduce overhead. Multiple
in-flight commands are not supported, although this could be resolved
with some FIFOs.
