ARM: 9327/1: vfp: Add missing VFP instructions to neon_support_hook

Add the missing "Unconditional Advanced SIMD and floating-point
instructions" in [1] to the VFP undef hook.

This commit addresses the issue reported in [2], where
executing the vudot instruction on a platform with FEAT_DotProd
support resulted in an undefined instruction error.
