crypto: hisilicon/sec2 - save capability registers in probe process

Browse source

[ Upstream commit f1115b0096 ]

Pre-store the valid value of the sec alg support related capability
register in sec_qm_init(), which will be called by probe process.
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.
