KVM: arm64: Key CPTR_EL2.E0POE propagation on FEAT_S1POE

Browse source

We propagate CPTR_EL2.E0POE from a L1 into the L0 configuration, but
we key this on the L1 guest supporting FEAT_S2POE. This is obviously
wrong, as this bit is solely concerned with Stage-1 translation.

Fix this by making the update depend on FEAT_S1POE.
