compat: provide compat_ptr() on all architectures
In order to avoid needless #ifdef CONFIG_COMPAT checks,
move the compat_ptr() definition to linux/compat.h
where it can be seen by any file regardless of the
architecture.
Only s390 needs a special definition, this can use the
self-#define trick we have elsewhere.
