Add ARMv8/AArch32 Crypto Extension implemenation of SHA-256
* cipher/Makefile.am: Add 'sha256-armv8-aarch32-ce.S'.
* cipher/sha256-armv8-aarch32-ce.S: New.
* cipher/sha256.c (USE_ARM_CE): New.
(sha256_init, sha224_init): Check features for HWF_ARM_SHA1.
[USE_ARM_CE] (_gcry_sha256_transform_armv8_ce): New.
(transform) [USE_ARM_CE]: Use ARMv8 CE implementation if HW supports.
(SHA256_CONTEXT): Add 'use_arm_ce'.
* configure.ac: Add 'sha256-armv8-aarch32-ce.lo'.
