ARM: KVM: promote vfp_host pointer to generic host cpu context
We use the vfp_host pointer to store the host VFP context, should the guest start using VFP itself. Actually, we can use this pointer in a more generic way to store CPU speficic data, and arm64 is using it to dump the whole host state before switching to the guest. Simply rename the vfp_host field to host_cpu_context, and the corresponding type to kvm_cpu_context_t. No change in functionnality.
