Vadim Bendebury 6cb2008348 uart: provide polling mode of operation ...

Early hardware bringup often is complicated by exceptions happening in
the code all over the place. Using interrupt based console output to
trace startup progress is inefficient - a lot of text gets buffered
and never shows up on the console.

The new config option enables the mode where the console output is
supposed to be happening in polling mode, the character transmit
function not exiting until the entire character is transmitted.

BRANCH=none
BUG=chrome-os-partner:43791
TEST=with the new config enabled (and the appropriate changes to
     chip/g/uart.c) was able to debug bringup on the new version.
