hw/ppc/spapr: Test whether TCG is enabled with tcg_enabled() 

Although the PPC target only supports the TCG and KVM
accelerators, QEMU supports more. We can not assume that
'!kvm == tcg', so test for the correct accelerator. This
also eases code review, because here we don't care about
KVM, we really want to test for TCG.
