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

Browse source

[ Upstream commit cf8b5156bb ]

Pre-store the valid value of hpre alg support related capability
register in hpre_qm_init(), which will be called by hpre_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.
