ARM: 9269/1: vfp: Add hwcap for FEAT_DotProd
Advanced Dot product is a feature present in AArch32 state for Armv8 and is represented by ISAR6 identification register. This feature denotes the presence of UDOT and SDOT instructions and hence adding a hwcap will enable the userspace to check it before trying to use those instructions.
