frv: add atomic64_add_unless()
[ Upstream commit 545d58f677b21401f6de1ac12c25cc109f903ace ]
The build of frv allmodconfig was failing with the error:
lib/atomic64_test.c:209:9: error:
implicit declaration of function 'atomic64_add_unless'
All the atomic64 operations were defined in frv, but
atomic64_add_unless() was not done.
Implement atomic64_add_unless() as done in other arches.
