printk: Constify name for add_preferred_console()
While adding a preferred console handling for serial_core for serial port
hardware based device addressing, Jiri suggested we constify name for
add_preferred_console(). The name gets copied anyways. This allows serial
core to add a preferred console using serial drv->dev_name without copying
it.
Note that constifying options causes changes all over the place because of
struct console for match().
