[SBUSFB]: implement ->compat_ioctl
This patch adds a new function, sbusfb_compat_ioctl() to
drivers/video/sbuslib.c and uses it as compat_ioctl in all sbus fb
drivers
This remove the last per-arch compat ioctl bits in
arch/sparc64/kernel/ioctl32.c so it would be nice if people could test
if this actually copiles and works and if yes apply it :)
