kvm_call_hyp() has some logic to issue a function call or a hypercall
depending the EL at which the kernel is running. However, all the code
compiled under __KVM_NVHE_HYPERVISOR__ is guaranteed to run only at EL2,
and in this case a simple function call is needed.

Add ifdefery to kvm_host.h to symplify kvm_call_hyp() in .hyp.text.
