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

[Doug Anderson]

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>
