crypto: fpu - Add template for blkcipher touching FPU
Blkcipher touching FPU need to be enclosed by kernel_fpu_begin() and kernel_fpu_end(). If they are invoked in cipher algorithm implementation, they will be invoked for each block, so that performance will be hurt, because they are "slow" operations. This patch implements "fpu" template, which makes these operations to be invoked for each request.
