crypto: hisilicon/zip - save capability registers in probe process

Browse source

[ Upstream commit 2ff0ad8479 ]

Pre-store the valid value of the zip alg support related capability
register in hisi_zip_qm_init(), which will be called by hisi_zip_probe().
It can reduce the number of capability register queries and avoid
obtaining incorrect values in abnormal scenarios, such as reset failed
and the memory space disabled.
