[POWERPC] spufs: Update SPU_Status[CISHP] in backing runcntl write
Currently, the kernel may fail to restart a SPE context which
has stopped and been swapped out.
This changes spu_backing_runcntl_write to emulate the real
SPU_Status register exactly. When the SPU Run Control register
is written with SPU_RunCntl[Run] set to '1', the physical SPU
automatically sets SPU_Status[R] and clears SPU_Status[CISHP].
