arm64: Expose support for optional ARMv8-A features
[ Upstream commit f5e035f8694c3bdddc66ea46ecda965ee6853718 ]
ARMv8-A adds a few optional features for ARMv8.2 and ARMv8.3.
Expose them to the userspace via HWCAPs and mrs emulation.
SHA2-512 - Instruction support for SHA512 Hash algorithm (e.g SHA512H,
SHA512H2, SHA512U0, SHA512SU1)
SHA3 - SHA3 crypto instructions (EOR3, RAX1, XAR, BCAX).
SM3 - Instruction support for Chinese cryptography algorithm SM3
SM4 - Instruction support for Chinese cryptography algorithm SM4
DP - Dot Product instructions (UDOT, SDOT).
