3.13.11.11 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Vineet Gupta <vgupta at synopsys.com>
commit 5c05483e2db91890faa9a7be0a831701a3f442d6 upstream.
There are certain test configuration of virtual platform which don't
have any real console device (uart/pgu). So add tty0 as a fallback console
device to allow system to boot and be accessible via telnet
Otherwise with ttyS0 as only console, but 8250 disabled in kernel build,
init chokes.
