[PATCH]x86_64: early_print kernel console should send CRLF not LFCR
in
commit d358788f3f30113e49882187d794832905e42592

Glen Turner reported that writing LFCR rather than the more
traditional CRLF causes issues with some terminals.
Since this aflicts many serial drivers, extract the common code
to a library function (uart_console_write) and arrange for each
driver to supply a "putchar" function.
but early_printk is left out.
