arch/arm: introduce generic FPU internal option
Currently, we consider that any VFP FPU is a superset of VFPv2, and thus
we use VFPv2 as a way to detect that a VFP is used.
However, for Cortex-M cores, the optional FPU is not a superset of
VFPv2; it is even not a VFP [0].
As a consequence, we can no longer consider VFPv2 as a indication that
an FPU is present.
So, we introduce two new internal options, BR2_ARM_CPU_MAYBE_HAS_FPU and
BR2_ARM_CPU_HAS_FPU, which we use to consider the presence of an FPU.
