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.
