crypto: qat - disable ZUC-256 capability for QAT GEN5

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.
