x86_64: early_print kernel console should send CRLF not LFCR
In commit d358788f3f30113e49882187d794832905e42592 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.
