DO NOT MERGE: use first available (boot) console by default

This allows to use any existing console kernel used before busybox.
So no need for explicit selection of "tty", this way produced rootfs
could be used with any Linux kernel on Hw with the same architecture but
different console ports.

But for this to work it's required to disable BR2_TARGET_GENERIC_GETTY.
