powerpc/spufs: remove class_0_dsisr from spu exception handling
According to the CBEA, the SPU dsisr is not updated for class 0 exceptions. spu_stopped() is testing the dsisr that was passed to it from the class 0 exception handler, so we return a false positive here. This patch cleans up the interrupt handler and erroneous tests in spu_stopped. It also removes the fields from the csa since it is not needed to process class 0 events.
