[PATCH v2 5/9] arm64/cpufeature: Use alternatives to check enabled ARM64_HAS_NMI feature

[Liao Chang]

Due to the historical reasons, cpus_have_const_cap() is more complicated
than it needs to be. When CONFIG_ARM64_NMI=y the ARM64_HAS_NMI cpucap is
a strict boot cpu feature which is detected and patched early on the
boot cpu, which means no code depends on ARM64_HAS_NMI cpucap run in the
window between the ARM64_HAS_NMI cpucap is detected and alternative is
patched. So it would be nice to migrate caller over to
alternative_has_cap_likey().
