Add support for remembering deconfigs without GUARD

 Currently on reconfig reboots only parts that are GUARDed
 are remembered and reapplied.
   - Add suport for a semi persisent PNOR partition,
     HB_VOLATILE which Hostboot uses to keep track of the reconfig
     reboots vs power off
   - Add a new GUARD type specifically for reconfig loops
   - Add RECALL_DECONFIG_ON_RECONFIG config flag to control
     what gets added to GUARD partition
   - During boot will add/clear guard records on deconfig based
     on config flags and semi persisent state.
