powerpc/spufs: synchronize interaction between spu exception handling and time slicing
Time slicing can occur at the same time as spu exception handling
resulting in the wakeup of the wrong thread.
This change uses the the spu's register_lock to enforce synchronization
between bind/unbind and spu exception handling so that they are
mutually exclusive.
