Pstates Support in OCC
1. Initialize Pstates global parameters (G_proc_fmax, G_proc_fmin,
G_khz_per_pstate and G_proc_pmin from the OCC Pstate Parameter
Block)
2. When frequency config data packet is received and OCC is NOT
already in Active state: Send IPC command to PGPE to set pState
clips to be wide open from min frequency to turbo
First verify min/max frequency from TMGT is within what
PGPE allows saved in G_proc_fmax and G_proc_fmin if not
within bounds trace and clip to G_proc_fmax/fmin)
3. Transition to active state: Send IPC command to PGPE to start
pState protocol (give correct data for OCC vs OPAL in control of
Pstates) and if OPAL system update OPAL shared memory with Pstate
information.
4. amec_slv_freq_smh(): Send IPC command to PGPE to set requested
pState (PowerVM) or set clips (OPAL).
5. Address all the TODO/TEMP/#if 0 in amec_freq.c either remove
or add RTC# for when it will be addressed
