In commit 4315f7c614743 we restructured the logic for creating the
VFP related properties to avoid testing the aa32_simd_r32 feature on
AArch64 CPUs.  However in the process we accidentally stopped
exposing the "vfp" QOM property on AArch32 TCG CPUs.

This mostly hasn't had any ill effects because not many people want
to disable VFP, but it wasn't intentional.  Reinstate the property.
