[PATCH]x86_64: early_print kernel console should send CRLF not LFCR
in
commit d358788f3f30113e49882187d794832905e42592
Author: Russell King <[email protected]>

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.
