STOP: Clear up todo items in STOP and mark them with RTC

1) add RTC marks for VDM/Xstop/CME Halt
2) add epm_p9_tunning for scan ratio
3) fix checking anep clock starts
4) fix large system default assuming header works now
5) poll for pfet sense line for power on/off
6) finalize panic upon fapi2 init fail in sgpe_main.c
