KVM: arm64: Make kvm_call_hyp() a function call at Hyp

Browse source

kvm_call_hyp() has some logic to issue a function call or a hypercall
depending on the EL at which the kernel is running. However, all the
code compiled under __KVM_NVHE_HYPERVISOR__ is guaranteed to only run
at EL2 which allows us to simplify.

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