arm64: Add compat hwcap I8MM

Browse source

This hwcap was added earlier for 32-bit native arm kernel by commit
956ca3a4eb ("ARM: 9272/1: vfp: Add hwcap for FEAT_AA32I8MM") and hence
the corresponding changes added in 32-bit compat arm64 kernel for similar
user interfaces.

Int8 matrix multiplication is a feature (FEAT_AA32I8MM) present in AArch32
state of Armv8 and is identified by ISAR6.I8MM register. Similar
feature(FEAT_I8MM) exist for AArch64 state and is already advertised in
arm64 kernel.
