Description: zipl: fix scsi dump.
Symptom:     Scsi dump does not work on LPAR with "ERROR: Could not 
	     enable dump device".
Problem:     The machine loader needs to find a gap in memory to store
	     some internal information after the first bootmap entry.
	     The current implementation leaves no space between first
	     and second entry. 
Solution:    Put the stage 3 loader as first entry into the bootmap.
