Control Host reboots for manufacturing

 In a manufacturing environment it is desired to reboot once
 (and only once) to get the FIRDATA analysis on checkstop.
 This commit adds functionality to control the auto reboot policy
 on the BMC.  It then "remembers" the state using the HB VOLATILE
 PNOR partition to enable reboots when in MFG mode.

 Note that when in this mode, any reboot (even from host) will
 terminate the boot.
