When KVM_CAP_PPC_ENABLE_HCALL was introduced, H_GET_TCE and H_PUT_TCE
were already implemented and enabled by default; however H_GET_TCE
was missed out on PR KVM (probably because the handler was in
the real mode code at the time).
This enables H_GET_TCE by default. While at this, this wraps
the checks in ifdef CONFIG_SPAPR_TCE_IOMMU just like HV KVM.
