As it stands now, the console effectively works in raw mode, so all
messages should end with "\r\n". This was missed previously, because
the sample was run in QEMU, on top of POSIX cooked console. Running
on real hardware showed this issue.

We have cases with UART drivers where TX interrupt handling is not
bootstrapped properly on enabling them. To make such cases more
obvious, start this sample with console_write(), the output of which
wouldn't appear if that's the case. (Of course, the sample starts
with printk() exlaining what may happpen.)
