As pointed by SAMA5D2 Datasheet[1]:
```
The Cortex-A5 NEON Media Processing Engine (MPE) extends the Cortex-A5
functionality to provide support for the ARM v7 Advanced SIMD v2 and
Vector Floating-Point v4 (VFPv4) instruction sets.
```

So let's enable VFPV4/NEON FPU strategy instead of the default VFPV4-D16.
