Clear ECC sections marked "clearOnEccErr" on error

  - Add the capability for Hostboot to recover (with reboot)
    when it consumes an ECC error
  - PNOR layout needs to be updated to flag the recoverable
    sections (generally cached or throw away data like *VPD
    HBEL, and GUARD partitions)
  - Upon bad ECC detection, Hostboot will check partition
    flag and if set, it will clear and write good ECC to PNOR.
    It will then throw the normal error and terminate, waiting
    for the BMC to issue a reboot
