s390/dump: remove SAVE_AREA_BASE
Replace the SAVE_AREA_BASE offset calculations in reipl.S with the
assembler constant for the location of each register status area.
Use __LC_FPREGS_SAVE_AREA instead of SAVE_AREA_BASE in the three
remaining code locations and remove the definition of SAVE_AREA_BASE.
