arm64: Add compat hwcap ASIMDBF16
This hwcap was added earlier for 32-bit native arm kernel by commit
23b6d4ad6e7a ("ARM: 9271/1: vfp: Add hwcap for FEAT_AA32BF16") and hence
the corresponding changes added in 32-bit compat arm64 kernel.
Brain 16-bit floating-point storage format is a feature (FEAT_AA32BF16)
present in AArch32 state for Armv8 and is represented by ISAR6.BF16
identification register. Similar feature (FEAT_BF16) exist for AArch64
state and is already advertised in native arm64 kernel.
