PGPE/CME Hcode: Safe Pstate and STOP<>VDM Fixes

- Set OVERRIDE_PSAFE_PSTATE=0(use psafe from GPPB) (PGPE)
- Make safe Pstate be lowest frequency limit (PGPE)
- Uses POWERSAVE if the safe mode frequency is not set.  Otherwise, uses the
  in the general clipping equation vs the safe computation (PGPE)
- Use the correct jump field (L_S) for setting safe mode (split variables for
  better understanding (HWP)
- Incorporate PGPE fix for registration doorbell acks as Safe Mode exacerbated
  a STOP 11 Quad Manager Registration timing window
- Fix CME DB0 ack window upon before QM registration
- Fix PGPE auto mode for Cronus
- Put CME Pstate analog update and Next Pstate update in critical section
  to fix testing issues
