asm-generic: move cmpxchg*_local defs to cmpxchg.h
asm/cmpxchg.h can be included on its own and needs to be self-consistent.
The definitions for the cmpxchg*_local macros, as such, need to be part
of this file.
This fixes a build issue on OpenRISC since the system.h smashing patch
96f951edb1f1bdbbc99b0cd458f9808bb83d58ae that introdued the direct inclusion
asm/cmpxchg.h into linux/llist.h.
