This hwcap was added earlier for 32-bit native arm kernel by commit
62ea0d87 ("ARM: 9269/1: vfp: Add hwcap for FEAT_DotProd") and hence the
corresponding changes added in 32-bit compat arm64 kernel for similar user
interfaces.

Advanced Dot product is a feature (FEAT_DotProd) present in both
AArch32/AArch64 state for Armv8 and is already advertised in native arm64
kernel.
