Like commit aa031b8f702e ("crypto: x86/sha512 - load based on CPU features"), these x86-optimized crypto modules already have module aliases based on CPU feature bits: ghash
Rename the unique device table data structure to a generic name so the code has the same pattern in all the modules.
This commit covers modules that created rcu stall issues due to kernel_fpu_begin/kernel_fpu_end calls.
