p9_pstate_parameter_block: Move to concise slope calculations

- Use loops over the set point vs explicit implementation to reduce
  critical code implementations
- Move slopes to float based calculation and then translate to I.F form
- Update dump output a bit; still need to add VDM thresholds to this
- Fix VDM related slope calculations
- rebased
- Data type change from float to double in threshold slope calculation
- rebased
