ARM: 9273/1: Add hwcap for Speculation Barrier(SB)
Speculation Barrier(FEAT_SB) is a feature present in AArch32 state for
Armv8 and is represented by ISAR6.SB identification register.
This feature denotes the presence of SB instruction and hence adding a
hwcap will enable the userspace to check it before trying to use this
instruction.
This commit adds the ID feature bit detection, and uses elf_hwcap2
accordingly.
