crypto: arm/aes-ce - stop using the SIMD helper

Now that ARM permits use of the NEON unit in softirq context as well as
task context, there is no longer a need to rely on the SIMD helper
module to construct async skciphers wrapping the sync ones, as the
latter can always be called directly.

So remove these wrappers and the dependency on the SIMD helper. This
permits the use of these algorithms by callers that only support
synchronous use.
