x86_64: early_print kernel console should send CRLF not LFCR 

In
	commit d358788f3f
	Author: Russell King <rmk@dyn-67.arm.linux.org.uk>
	Date:   Mon Mar 20 20:00:09 2006 +0000

Glen Turner reported that writing LFCR rather than the more
traditional CRLF causes issues with some terminals.

Since this afflicts 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.
