According to the logical layering of UADK, the device driver has been updated from the previous fixed binding HiSilicon accelerator to the dynamic registration method through the algorithm linked list method.

After the update, it can support the use of instruction acceleration and third-party device drivers.

After the dynamic loading function is added, device resource initialization, driver acquisition, and scheduler initialization functions need to be extracted into the public framework.

so that the algorithm can quickly adapt to the dynamic loading function internally.

1. Add the init2 interface for the cipher algorithm to simplify the user's use of the cipher algorithm.

2. After adding the cipher module of the init2 interface, combine it Dynamically load the initialization part, transform HiSilicon sec driven, and implemented using the dynamic loading function Connection between driver and algorithm layer.
