Wrap the helpers for getting references to KVM instances with a check on CONFIG_KVM being enabled, not on CONFIG_HAVE_KVM being defined. PPC does NOT select HAVE_KVM, despite obviously supporting KVM, and guarding code to get references to KVM based on whether or not the architecture supports KVM is nonsensical. Drop the guard around linux/kvm_host.h entirely, conditionally including a generic headers is completely unnecessary.
