console: Do not translate `\n` to `\r` in CBMEM console

coreboot messages written to CBMEM console and read with `cbmem -c`,
    currently have a control character at the end.

coreboot-4.0-5833-gcf7b498 Mon Apr 28 09:53:22 CEST 2014 booting...^M

This happens in the function `printk()` where a new line character
    `\n` is replaced by a carriage return character `\r` in the function
    `printk()`. This was introduced for serial/UART consoles, but is not
    needed for CBMEM console. So do not replace the new line character
    there.

The logic is only changed for CBMEM console but the change is probably
    also useful for other consoles.
