crypto: hisilicon - re-enable address prefetch after device resuming
When the device resumes from a suspended state, it will revert to its
initial state and requires re-enabling. Currently, the address prefetch
function is not re-enabled after device resuming. Move the address prefetch
enable to the initialization process. In this way, the address prefetch
can be enabled when the device resumes by calling the initialization
process.
