haswell: check for clean reset
When an INIT# is delivered to the CPU the CPU starts executing from the reset vector. However, the internal state is maintained. Therefore, check for such a condition and reset the system. Issues 'apreset warm' on the EC console. INIT# is sent and CPU notices it's not a clean reset and forces one. No hangs.
