This hwcap was added for 32-bit native arm kernel by commit
3bda6d8848 ("ARM: 9273/1: Add hwcap for Speculation Barrier(SB)")
and hence the corresponding changes added in 32-bit compat arm64 kernel.

Speculation Barrier is a feature(FEAT_SB) present in both AArch32 and
AArch64 state. This hwcap is already advertised in native arm64 kernel.
