uart: Enable buffering the FIFO.
...
On the iCE40 FPGA, adding buffering allows the SyncFIFO to be placed in
block RAM rather than consuming a large amount of resources.

sim: serial: Send '\r\n' instead of just '\n'
...
This fixes an issue when running with the HDMI2USB firmware which
expects \r\n to come from the UART. Since the verilator adapter
is just sending \n commands cannot be executed.
Also, one minor whitespace cleanup. (could remove if needed)
