WOF: Pass PGPE VPD IQ good normal core per sort for WOF Phase 2
- p9_pstate_parameter_block fills in repurposed Pstate options field
- PGPE checks for non-zero value and uses for number of cores in vratio calc
- Forward and backward compatible with present (bad) behavior; both Hostboot
and Hcode must both be present for correct behavior
- Update p9_dump_pstate_table tool HWP (not consumed by FW). However, it uses
the update p9_pstates_pgpe.h, Overlay structure compatible with back levels
of p9_dump_pstate_table_wrap tool
