arm64: Add support of PAuth QARMA3 architected algorithm
QARMA3 is relaxed version of the QARMA5 algorithm which expected to
reduce the latency of calculation while still delivering a suitable
level of security.
Support for QARMA3 can be discovered via ID_AA64ISAR2_EL1
APA3, bits [15:12] Indicates whether the QARMA3 algorithm is
implemented in the PE for address
authentication in AArch64 state.
GPA3, bits [11:8] Indicates whether the QARMA3 algorithm is
implemented in the PE for generic code
authentication in AArch64 state.
