Add missing logic to allow in-kernel VFP usage for ARMv7 NEON. The implementation is strongly based on arm64 code. It introduces a family of fpu_kern_* functions to enable the usage of VFP instructions in kernel. Apart from that the existing armv7 VFP logic was modified, taking into account that the state of the VFP registers can now be modified in the kernel.
