8aa3fb3eb7 com/uart: add tx and rx fifos. 
Since ressource usage is low with default depth of 16 (implemented in RAM LUTs) we don't keep old behaviour.
Tested successfully with BIOS and flterm.

1a4a6eb445 Copy some software code from the original Milkymist SoC. 
Libbase should keep its RAM usage to a minimum as it is meant to
be executed before the SDRAM is up and running. (Having lots of
code is OK though as we XIP from the flash)
