arm64: cpufeature: Fix mismerge of CONFIG_ARM64_SSBD block
When merging support for SSBD and the CRC32 instructions, the conflict resolution for the new capability entries in arm64_features[] inadvertedly predicated the availability of the CRC32 instructions on CONFIG_ARM64_SSBD, despite the functionality being entirely unrelated. Move the #ifdef CONFIG_ARM64_SSBD down so that it only covers the SSBD capability. Signed-off-by: Will Deacon <will.deacon@arm.com> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
