Dynamic ATTR Override support via debug interface

  -Supported by debug tools (ecmd-debug-framework/Cronus)
    Only in istep mode and between isteps
    Requires HB to be running
  -Uses output of attributeOverride tool (same format as ATTR_TMP)
  -Introduces two new "debug" isteps
     255,4,set_attr_overrides
     255,5,clear_attr_overrides
  -Once istep is triggered Hostboot sends down address/size
    and the debug tool uses putmempba to push data to cache/mem.
    Then Hostboot consumes just like ATTR_TMP
