crypto: hisilicon - re-enable address prefetch after device resuming

Browse Source 
[ Upstream commit 0dcd21443d9308ed88909d35aa0490c3fc680a47 ]

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.
