Power off does not seem to use the ACPI _OFF function, but rather the
smihandler. Creating variant_smi_sleep function for nami to handle
the power off sequence during reboot/power off.
BUG=b:78311818
BRANCH=None
TEST=Run "poweroff" command from AP console with SMI_DEBUG enabled
Make sure delays are consistent with spec

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.
BUG=b:63903239
TEST= Build for Soraka. Check Camera probe, Capture image across
S3 & S0ix cycles.
Also checked the following & found no regression:
1. Typical camera use cases
2. Stability tests related to camera
3. Reliability tests related to camera
4. PnP tests related to camera
5. Latency related tests with camera

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
whether PMIC internal registers state are preserved.

In order to be able to share code across different poppy variants,
provide the concept of baseboard and variants. New directory layout:
variants/baseboard - code
variants/baseboard/include/baseboard - headers
variants/poppy - code
variants/poppy/include/variant - headers
New boards would then add themselves under their board name within
"variants" directory.
This is purely an organizational change.
