arm64: cpufeature: remove duplicate ID_AA64ISAR2_EL1 entry

The ID register table should have one entry per ID register but
currently has two entries for ID_AA64ISAR2_EL1. Only one entry has an
override, and get_arm64_ftr_reg() can end up choosing the other, causing
the override to be ignored. Fix this by removing the duplicate entry.

While here, also make the check in sort_ftr_regs() more strict so that
duplicate entries can't be added in the future.
