arch/ia64/include: remove CONFIG_IA64_DEBUG_CMPXCHG from uapi header

CONFIG_* switches should not be exposed in uapi headers.  The macros that
are defined here are also only useful for the kernel code, so let's move
them to asm/cmpxchg.h instead.

The only two files that are using these macros are the headers
arch/ia64/include/asm/bitops.h and arch/ia64/include/asm/atomic.h and
these include asm/cmpxchg.h via asm/intrinsics.h, so this movement should
not cause any trouble.
