The open interface of the sva prefetching function is distinguish the chip
version. But the close interface of the sva prefetching function doesn't
distinguish the chip version. As a result, the sva prefetching close
operation is also performed on Kunpeng920, those registers are important
on Kunpeng920, which eventually leads to abnormal hardware problems. So
need to fix it immediately.
