(CMOS input) in the Baby Jaguar platform.

(AVIP's need to be started before the MPIF's in order to have a good clock distribution).
AVIP default power-up mode is Standby. The Viper instructs AVIP via I²C to enable all the
PLL's and clocks and hence enter to Full Power mode. See FMS AVIP for further details
and the rest of the initialization.
MPIF's should be initialized according the FMS information.
MPIF should deliver 2 observers:
POR= 0; normal operation
ROK = 1; reference frequency is present (coming from AVIP)
Do not enter semi-standby state in case of an LPL
scanning backlight LCD set before 4s preheating timer has
