Todd Broch 1fc8e63681 Add uart_prefix flag to control which uart is used to flash.
There are CrOS devices that have multiple embedded controllers and
therefore multiple uarts that can be used for programming.

This CL allows user to set the uart_prefix to access the alternate
uarts via the --uart_prefix argument.  Default is still 'ec'.
