arm64: Fix match_list for erratum 1286807 on Arm Cortex-A76
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.
