[PATCH] TIOC* compat ioctl handling

TIOCSTART and TIOCSTOP are defined in asm/ioctls.h and asm/termios.h by
various architectures but not actually implemented anywhere but in the IRIX
compatibility layer, so remove their COMPATIBLE_IOCTL from parisc, ppc64
and sparc64.

Move the TIOCSLTC COMPATIBLE_IOCTL to common code, guided by an ifdef to
only show up on architectures that support it (same as the code handling it
in tty_ioctl.c), aswell as it's brother TIOCGLTC that wasn't handled so
far.
