Pstate Parameter Block/Setup Evid: Safe Pstate Fix

- Use the correct jump field (L_S) for setting safe mode (split variables for
  better understanding (HWP)
- General rearrangement of the safe mode calculations to perform proper voltage
  uplift (HWP)
- Added HWP only consumed elements to common headers (no co-reqs with Hcode!)
- Correct VDN and VCS voltage handling for biases
- Added VDM jump values to the GPPB for dumping via memory tools. Proven useful
  for VDM debug.
- Fix biases
- Deal with Cronus manual mode setting of Safe Mode
- Add check that Safe Mode is not above UltraTurbo
- Clip freq2pState to positive frequencies
- Add check that Boot Frequency is not above UltraTurbo
