Fix FRV cmpxchg_local

Fix the FRV cmpxchg_local by breaking the following header dependency loop :

linux/kernel.h -> linux/bitops.h -> asm-frv/bitops.h -> asm-frv/atomic.h
  -> asm-frv/system.h ->
  asm-generic/cmpxchg_local.h -> typecheck() defined in linux/kernel.h

and

linux/kernel.h -> linux/bitops.h -> asm-frv/bitops.h -> asm-frv/atomic.h ->
  asm-generic/cmpxchg_local.h -> typecheck() defined in linux/kernel.h

In order to fix this :
- Move the atomic_test_and_ *_mask inlines from asm-frv/atomic.h (why are they
  there at all anyway ? They are not touching atomic_t variables!) to
  asm-frv/bitops.h.

Also fix a build issue with cmpxchg : it does not cast to (unsigned long *)
like other architectures, to deal with it in the cmpxchg_local macro.

FRV builds fine with this patch.

Thanks to Adrian Bunk <bunk@kernel.org> for spotting this bug.
