Currently the u-boot output looks rather odd when running the minicom
terminal emulator in its default mode (just a string of "random" looking
text down the right hand side of the screen).
This is caused by a combination of minicom not automatically wrapping
lines and the stm32 serial driver never sending a carriage return.
Issue is trivially solved by automatically generating a CR whenever a LF
is transmitted, Several other serial drivers implement this behaviour.
