crypto: hisilicon/sec - fix the process of disabling sva prefetching
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. Signed-off-by: Kai Ye <yekai13@huawei.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
