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

   in 
	commit d358788f3f30113e49882187d794832905e42592
	Author: Russell King <rmk@xxxxxxxxxxxxxxxxxxxxxxx>

    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.
