MPIPL: Define OPAL metadata area
We want to save some information (like crashing CPU PIR, kernel tags,
etc) before triggering MPIPL. Post MPIPL we will use this information
to retrieve dump metadata and create dump.
MDRT table doesn't need 64K. Hence split MDRT table to accommodate
metadata area.
Finally define metadata structure.
