Subject: [PATCH 5.10 79/86] arm64: Fix match_list for erratum 1286807 on Arm Cortex-A76

From: Zenghui Yu <yuzenghui@...wei.com>

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.

Fixes: 51f559d66527 ("arm64: Enable repeat tlbi workaround on KRYO4XX gold CPUs")
