New subject: [PATCH 2/5] crypto: hisilicon/qm - save capability registers in qm init process

In reset scenario, if reset failed after disabling the MSE, the value of capability registers will become invalid. If we remove the device under this situation, the unregister process will get the wrong irq vector, and can not get the right irq number by pci_irq_vector(). This will cause the following call trace:

So add a capability table structure to pre-store the valid value of the capability register in qm init process, avoid obtaining invalid capability register value after the MSE is disabled.

New subject: [PATCH 3/5] crypto: hisilicon/hpre - save capability registers in probe process

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.

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.
