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.
