[PATCH 1/2] hwf-arm: add ARMv8.2 optional crypto extension HW features

[Tianjia Zhang]

* src/g10lib.h (HWF_ARM_SHA3, HWF_ARM_SM3, HWF_ARM_SM4)
(HWF_ARM_SHA512): New.
* src/hwf-arm.c (arm_features): Add sha3, sm3, sm4, sha512 HW features.
* src/hwfeatures.c (hwflist): Add sha3, sm3, sm4, sha512 HW features.
