tty: deprecate tty_write_message()
tty_write_message() has only one user: quotas. In particular, there the use depends on CONFIG_PRINT_QUOTA_WARNING. And that is deprecated and marked as BROKEN already too. So make tty_write_message() dependent on that very config option. This action in fact drops tty_write_message() from the vmlinux binary. Good riddance.
