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
