crypto: qat - disable ZUC-256 capability for QAT GEN5
[ Upstream commit d956692c7dd523b331d4556ee03def8dd02609dc ]
The ZUC-256 EEA (encryption) and EIA (integrity) algorithms are not
supported on QAT GEN5 devices, as their current implementation does not
align with the NIST specification. Earlier versions of the ZUC-256
specification used a different initialization scheme, which has since
been revised to comply with the 5G specification.
Due to this misalignment with the updated specification, remove support
for ZUC-256 EEA and EIA for QAT GEN5 by masking out the ZUC-256
capability.
