From: Tzu-Jung Lee <tjlee at ambarella.com>
We ran into a "Login incorrect" problem when running the same rootfs
image across platforms with different loging ports ttyS0/1/2/3.
Simply assignning "console" to BR2_TARGET_GENERIC_GETTY_PORT, which in
turn modifies the /etc/inittab, is not enough because the "console" device
was missing in the /etc/securetty.
While current securetty has enumerated a lot of ttys, this patch should save
some efforts to enumerate more.
