get-reg-list includes ZCR_EL2 in the list of EL2 registers that it looks for when NV is enabled but does not have any feature gate for this register, meaning that testing any combination of features that includes EL2 but does not include SVE will result in a test failure due to a missing register being reported:
| The following lines are missing registers: | | ARM64_SYS_REG(3, 4, 1, 2, 0),
Add ZCR_EL2 to feat_id_regs so that the test knows not to expect to see it without SVE being enabled.
