hdata: Split MDST 'type' field to accommodate MPIPL
The MPIPL facility needs to store region and type information
corresponding with each MDST entry.
- data region : dump data regions (like DUMP_REGION_* )
- dump type : Reflects MDST entry usage (used by SYSDUMP -OR- FADUMP)
The existing type field is currently not used by FSP and/or firmware, so it
is safe to re-purpose it.
