Fix below sparse warnings introduced while adding errata.
arch/arm64/kernel/cpu_errata.c:218:25: sparse: warning: symbol
'cavium_erratum_23154_cpus' was not declared. Should it be static?
arch/arm64/kernel/cpu_errata.c:233:25: sparse: warning: symbol
'cavium_erratum_27456_cpus' was not declared. Should it be static?

That's referred in arch/arm64/kernel/cpufeature.c, so the build fails.
