Currently PMIC (tps68470) is in active state even when cameras are not
in use. PMIC is put into SLEEP mode only when entering S3 via
smihandler.
With this change PMIC will be put into SLEEP mode as soon as sensors &
VCM voltage outputs are turned off. This will allow run time power
saving when camera is not in use.
PMIC will be reset in first boot & across S3 & S0ix cycles.
Also, remove the smi handler for PMIC power management & handle it as
part of sensor and VCM ACPI PowerResource.

GPP_B8 acts as input to the inverter whose output controls PERST#
signal to wifi module. Out of reset, GPP_B8 is configured as
input by default. Since there is no external pull-down on it, this
line is floating and results in PERST# being asserted until ramstage
where the GPIO was originally configured. Because of this the wifi
chip is not ready during the PCIe initialization step. Move the
configuration of GPP_B8 to bootblock so that wifi device is taken out
of reset as early as possible.

1. Due to reset signal, PMIC loses its internal register state. This
causes PMIC to be in improper state after sleep.
2. The intent of reset signal is to reset internal state of PMIC (which
happens once during power on), hence avoid asserting reset signal
when not needed.
3. As per PMIC (TPS68470) datasheet, device can be kept in SLEEP mode
when not in use to save max possible power.
To fix the same, do not reset PMIC while entering sleep.
By keeping PMIC in SLEEP mode, Power consumption is < 1uW (Typ) upto
3.63uW (Max). Refs: TPS68470 datasheet.
Measured value: 0.66uW
TEST= Build the firmware for Soraka & boot to OS. Do S3 resume & check
