[PATCH] kdb: Put a cr before lf when working w/ a non open console port

From: Doug Anderson
Date: Fri Apr 18 2014 - 13:19:01 EST


In (efe2f29 kgdboc,kdb: Allow kdb to work on a non open console port)
support was added to directly use the "write_char" functions when
doing kdb over a non-open console port. This is great, but it ends up
bypassing the normal code in uart_console_write() that adds a carriage
return before any newlines.

Add similar code in kdb so we don't get things like:
[0]kdb>
[0]kdb>
[0]kdb>
