warm-reboot: ensure sbe start bit is 0

Cold reboots assume the SBE start bit (P9_CBS_REG, bit 0) will start out
with a value of 0. When the chassis power is cycled, this is a valid
assumption. However, when doing a warm reboot (chassis power remains on)
this is not a valid assumption.

The SBE depends on seeing the 0->1 transition of this bit to know when
to start the host. To support warm reboots, ensure the bit starts at 0.
