target-ppc: Move cpu_exec_init() call to realize function 

Move cpu_exec_init() call from instance_init to realize. This allows
any failures from cpu_exec_init() to be handled appropriately.
Also add corresponding cpu_exec_exit() call from unrealize.

cpu_dt_id assignment from instance_init is no longer needed since
correct assignment for cpu_dt_id is already present in realizefn.
