TTY: export NR_LDISC and N_* line discipline numbers to user-space
Since commit (4564f9e5: consolidate line discipline number definitions) the patch moved all line discipline number from a per-architecture termios.h to a shared one: tty.h. However, prior to this consolidation work, the line discipline numbers were outside of an ifdef __KERNEL__/endif block so these numbers used to be exported to user-space. Since such numbers are kernel ABI anyway, and tty.h is already included for user- space header processing, just move these relevant defines outside of the ifdef __KERNEL__/endif block in include/linux/tty.h.
