Hyper-V emulation in KVM is a fairly big chunk and in some cases it may be desirable to not compile it in to reduce module sizes as well as the attack surface. Introduce CONFIG_KVM_HYPERV option to make it possible. Note, there's room for further nVMX/nSVM code optimizations when !CONFIG_KVM_HYPERV, this will be done in follow-up patches. Reorganize Makefile a bit so all CONFIG_HYPERV and CONFIG_KVM_HYPERV files are grouped together.
