[PATCH] TIOC* compat ioctl handling

[Christoph Hellwig <hch@lst.de>]

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.
