[PATCH v2 6/8] hvf: arm: Mark CPU as dirty on reset |

When clearing internal state of a CPU, we should also make sure that HVF
knows about it and can push the new values down to vcpu state.
Make sure that with HVF enabled, we tell it that it should synchronize
CPU state on next entry after a reset.
This fixes PSCI handling, because now newly pushed state such as X0 and
PC on remote CPU enablement also get pushed into HVF.
