commit 5e1e087457c94ad7fafbe1cf6f774c6999ee29d4 upstream.
Since commit 51f559d66527 ("arm64: Enable repeat tlbi workaround on KRYO4XX gold CPUs"), we failed to detect erratum 1286807 on Cortex-A76 because its entry in arm64_repeat_tlbi_list[] was accidently corrupted by this commit.
Fix this issue by creating a separate entry for Kryo4xx Gold.
