This hwcap was added for 32-bit native arm kernel by commit fea53546
("ARM: 9274/1: Add hwcap for Speculative Store Bypassing Safe") and hence
the corresponding changes added in 32-bit compat arm64 for similar user
interfaces.

Speculative Store Bypass Safe is a feature(FEAT_SSBS) present in
AArch32/AArch64 state for Armv8 and can be identified by PFR2.SSBS
identification register. This hwcap is already advertised in native arm64
kernel.
