[PATCH 2/2] tty: Change order of ttynull to be loaded sooner.

[adamsimonelli]

From: Adam Simonelli <adamsimonelli@xxxxxxxxx>

If CONFIG_NULL_TTY_CONSOLE is enabled, and CONFIG_VT is disabled, ttynull
will become the default primary console device, based on the load order.
Users and distributions that are migrating away from CONFIG_VT will
benefit from this as /dev/console would not suddenly become /dev/ttyS0
which could otherwise cause some user space behavior changes, namely the
TCGETS ioctl failing, which causes libc's isatty() to incorrectly return
false when /dev/ttyS0 is disabled, and will prevent a device that is
connected to a user's /dev/ttyS0 to suddenly start getting kernel log
messages.
