[POWERPC] spufs: Use SPU master control to prevent wild SPU execution

Browse source

When the user changes the runcontrol register, an SPU might be
running without a process being attached to it and waiting for
events. In order to prevent this, make sure we always disable
the priv1 master control when we're not inside of spu_run.
