Since commit aefbab8e77eb ("arm64: fpsimd: Preserve/restore kernel mode
NEON at context switch"), kernel-mode NEON sections have been
preemptible on arm64.  And since commit 7dadeaa6e851 ("sched: Further
restrict the preemption modes"), voluntary preemption is no longer
supported on arm64 either.  Therefore, there's no longer any need to
limit the length of kernel-mode NEON sections on arm64.

This series simplifies the code in lib/crypto/arm64/ accordingly by
using longer kernel-mode NEON sections instead of multiple shorter ones.

This series is targeting libcrypto-next.
