tty: tty_ldisc: Fix some kernel-doc related misdemeanours
- Functions must follow directly on from their headers
- Demote non-conforming kernel-doc header
- Ensure notes have unique section names
- Provide missing description for 'reinit'
Fixes the following W=1 kernel build warning(s):
drivers/tty/tty_ldisc.c:158: warning: cannot understand function prototype: 'int tty_ldisc_autoload = IS_BUILTIN(CONFIG_LDISC_AUTOLOAD); '
drivers/tty/tty_ldisc.c:199: warning: Function parameter or member 'ld' not described in 'tty_ldisc_put'
drivers/tty/tty_ldisc.c:260: warning: duplicate section name 'Note'
drivers/tty/tty_ldisc.c:717: warning: Function parameter or member 'reinit' not described in 'tty_ldisc_hangup'
