Sean Anderson 58cebe5ac2 uart_tx: Fix AXIS handshaking 
AXI stream data is transferred based on the current values of the signals,
not the previous ones. This will cause problems if the other end isn't
valid all the time. Fix this, and amend the testbench to test it.

Fixes: e44d381 ("Add UART transmit module")

Sean Anderson e44d381c20 Add UART transmit module 
I join everyone and their mother in creating my own UART. 8n1 only, and 2
baud rates. Accepts AXI-stream.
